A television pilot (also known as a pilot or a pilot episode and sometimes marketed as a tele-movie) is a standalone episode of a television series that is used to sell the show to a television network. At the time of its creation, the pilot is meant to be the testing ground to gauge whether a series will be successful. It is, therefore, a test episode for the intended television series, an early step in the series development, much like pilot studies serve as precursors to the start of larger activity.
In the case of a successful television series, the pilot is commonly the first episode that is aired of the particular series under its own name; the episode that gets the series "off the ground". A "backdoor pilot" is an episode of an existing successful series, featuring future tie-in characters of an up-and-coming television series or film. Its purpose is to introduce the characters to an audience before the creators decide on whether or not they intend to pursue a spin-off series with those characters.
Television networks use pilots to determine whether an entertaining concept can be successfully realized and whether the expense of additional episodes is justified. A pilot is best thought of as a prototype of the show that is to follow, because elements often change from pilot to series. Variety estimates that only a little over a quarter of all pilots made for American television proceed to the series stage. Most pilots are never publicly screened if they fail to sell a series.
The examples and perspective in this article deal primarily with the United States and do not represent a worldwide view of the subject. (October 2015) (Learn how and when to remove this template message)
Each summer, the major American broadcast television networks - including ABC, CBS, The CW, Fox, and NBC - receive about 500 brief elevator pitches each for new shows from writers and producers. That fall, each network requests scripts for about 70 pitches and, the following January, orders about 20 pilot episodes. Actors come to Los Angeles from within the area or elsewhere in the United States and around the world to audition for them. By spring, actors are cast and production crews assembled to produce the pilots.
Casting is a lengthy and very competitive process. For the 1994 pilot of Friends, casting director Ellie Kanner reviewed more than 1,000 actors' head shots for each of the six main roles. She summoned 75 actors for each role to audition, then chose some to audition again for the show's creators. Of this group, the creators chose some to audition again for Warner Bros. Television executives, who chose the final group of a few actors to audition for NBC executives; as they decide whether to purchase a pilot, network executives generally have ultimate authority over casting. Since the networks work on the same shared schedule, directors, actors and others, must choose the best pilot to work for with the hopes that the network will choose it. If it is not chosen, they have wasted their time and money and may have missed out on better career opportunities.
Once they have been produced, the pilots are presented to studio and network executives, and in some cases to test audiences; at this point, each pilot receives various degrees of feedback and is gauged on its potential to advance from one pilot to a full-fledged series. Using this feedback, and factoring in the current status and future potential of their existing series, each network chooses about four to eight pilots for series status. The new series are then presented at the networks' annual upfronts in May, where they are added to network schedules for the following season (either for a fall or "mid-season" winter debut), and at the upfront presentation, the shows are shown to potential advertisers and the networks sell the majority of the advertising for their new pilots. The survival odds for these new series are low, as typically only one or two of them survive for more than one season.
A premise pilot introduces the characters and their world to the viewer; it is structured so that it can be run as the first episode of the series if substantial changes are not made between the pilot and greenlighting. In the event the changes being made are so substantial that they would cause confusion to viewers, the pilot (or portions of it) is often re-shot, recast, or rewritten to fit the rest of the series.
The pilot for Gilligan's Island, for instance, showed the castaways when they had just become stranded on the island. However, three roles were recast before going to series, with the characters either modified or completely altered to the point where the pilot could no longer be used as a regular episode. As a result, CBS aired Gilligan's second produced episode, which opened with the same scene of the characters just stranded on the island (showing only those not re-cast), first; the story from the pilot from that point onward was largely reworked into a flashback episode which aired later (with several key scenes re-shot). Even Gilligan's theme song, which was originally done as a calypso number, was rewritten and recomposed to be completely different.
Another example was in the original Star Trek where most of the footage of the original pilot, "The Cage," was incorporated into the acclaimed two-part episode, "The Menagerie," with the story justification that it depicted events that happened several years earlier. Conversely, the second pilot for Star Trek, "Where No Man Has Gone Before", aired as the third episode of the show's first season, even though it included some casting and costuming differences that set it apart from the preceding episodes (enough that a literary work based on one of its spin-offs would actually place the episode in a parallel universe).
If a network orders a two-hour pilot, it will usually broadcast it as a television film to recoup some of the costs even if the network chooses to not order the show. Sometimes, a made-for-TV-movie is filmed as the pilot, but because of actors not being available, the series intro is reshot and the first reshot episode is considered the pilot. The original Cagney & Lacey movie co-starred Loretta Swit (of M*A*S*H fame) as Chris Cagney, but when she could not get out of her contract, they reshot it with Meg Foster, who after the first season was replaced with Sharon Gless; therefore, the original movie is not considered a pilot, and is not included in the series collections on DVD. In some cases, this does not hamper broadcast, such as Jackie Cooper playing the role of Walter Carlson in the TV movie pilot of the 1975 series The Invisible Man, but being replaced by Craig Stevens for the remainder of the series; the pilot is still considered part of the series and released to DVD as such. Likewise, The Homecoming: A Christmas Story had an almost entirely different cast from the series it was intended to pilot (The Waltons), but both have been rerun for many years.
A proof of concept pilot usually takes place chronologically further into a series run than a premise pilot, to give network executives a better feel for how a typical episode would appear (since a premise pilot may have to deviate from a typical episode in order to properly introduce characters). Remington Steele used both a proof of concept and a premise pilot. Proofs of concept were particularly common for game shows; in such cases, the pilot may be entirely or partially scripted (and thus, due to regulations passed after the 1950s quiz show scandals, illegal to broadcast in many jurisdictions) and use fake contestants and "returning champions" to demonstrate those concepts. The adventure series Lassie had both a premise pilot, "The Inheritance", designed specifically to air as the series' first episode, showing how Lassie's series owner, Jeff Miller, came to acquire her; and a proof of concept pilot, "The Well", showcasing situations typical to the series, which aired well on into season 1 of the series.
A backdoor pilot is a film or miniseries that serves as a proof of concept for a full series, but may be broadcast on its own even if the full series is not picked up. The term may also be used for an episode of a currently running show that serves to introduce a spin-off. Such backdoor pilots commonly focus on an existing character or characters from the parent series who are to be given their own show.
For example, to introduce A Different World, built around Cosby Show character Denise Huxtable (Lisa Bonet), the Cosby Show episode "Hillman" was devoted to Denise's visit to the college that would become the new show's setting, and her encounters with some of the new show's supporting characters. A 2018 episode of ABC's 1980s-set sitcom The Goldbergs, titled "1990-Something", heavily featured teachers who were recurring characters on the series and served as the backdoor pilot to Schooled, which debuted in early 2019.
In other cases, however, an episode of the parent show may also focus on one or more guest characters who have not previously appeared in the show; for example, the JAG season eight episodes "Ice Queen" and "Meltdown" introduced the characters for what would become NCIS, while the NCIS season six two-part episode "Legend" introduced the characters for what would become the NCIS spin-off series NCIS: Los Angeles, and the NCIS season 11 two-part episode "Crescent City" introduced the characters for what would become NCIS: New Orleans. NCIS: Los Angeles itself also included a backdoor pilot for a potential further spin-off - NCIS: Red - but the series was not picked up. 
Similarly, the backdoor pilot for the television sitcom Empty Nest was an episode of The Golden Girls, which relegated that show's regular stars to supporting characters in an episode devoted to new characters who were introduced as their neighbors. Feedback on the episode resulted in Empty Nest being extensively reworked before its debut; while the concept and the "living next to the Golden Girls" setting was retained, the series ended up featuring different characters from those in the original Golden Girls episode.
In a 2011 episode of the TV Land original sitcom Hot in Cleveland focused on the wedding of the Elka character (Betty White). Boyce Ballentine (Cedric the Entertainer), an R&B singer-turned-preacher, was introduced as the pastor for the wedding, with the intention to give the Boyce character his own series on the network. That came to fruition in 2012, when TV Land introduced The Soul Man.
Not all backdoor pilots lead to a series. In 1968, the Star Trek episode "Assignment: Earth" was intended as the pilot for a spin-off of the same name, featuring a human named Gary Seven (played by Robert Lansing), taken from Earth's far past and raised by aliens to be sent to watch over Earth in the 1960s; while the series was not picked up, its characters have appeared in numerous non-canon Trek productions set in the 20th century.
ABC attempted to create a spin-off of Charlie's Angels in 1980 called Toni's Boys. The backdoor pilot that aired near the end of season four was simply titled "Toni's Boys" (season 4, episode 23) and guest starred Barbara Stanwyck as Antonia "Toni" Blake, a wealthy widow and friend of Charlie Townsend's who ran a detective agency. The agency was staffed by three handsome male detectives--Cotton Harper (Stephen Shortridge), Matt Parrish (Bruce Bauer), and Bob Sorensen (Bob Seagren)--who took direction from Toni and solved crimes in a manner similar to the Angels. The show was not picked up as a regular series for the following season.
The series finale of One Day at a Time in May 1984 was supposed to serve as a backdoor pilot to a spin-off featuring Pat Harrington, Jr.'s character of Dwayne Schneider in a new setting, but CBS ultimately passed on the potential series. Similarly, the 1988 two-part series finale of The Facts of Life ("The End of the Beginning" and "The Beginning of the Beginning") also served as a backdoor pilot that focused on the decision Blair Warner (Lisa Whelchel) made in using her trust fund to purchase the financially troubled Eastland Academy. Blair became headmistress and opened enrollment to male students for the first time in Eastland history. Up-and-coming actors Juliette Lewis, Mayim Bialik, Seth Green, and Meredith Scott Lynn were featured as some of Eastland's new students. NBC did not pick up the new series.
The Dukes of Hazzard aired two episodes, named "Jude Emery" and "Mason Dixon's Girls", which served as a backdoor pilot complete with the Dukes cast interacting with the new characters. Ultimately, CBS passed on the two series in favor of a series starring Hazzard County deputy Enos Strate. Another example within sitcoms would be a season 2 episode of The Nanny called "The Chatterbox", which centered around a struggling actress who gets a job at a barbershop owned by a single father.
In an example from June 2010, Lifetime pursued a spinoff procedural drama of Army Wives featuring Brigid Brannagh's character, police officer Pamela Moran. The fourth-season episode "Murder in Charleston" was intended to serve as a backdoor pilot for the proposed spin-off. The episode sees Moran teaming up with an Atlanta-based detective on a murder that is related to a case she has been working on for the past three years. At the end of the episode, the detective encourages Moran to take a detective's exam, and to look for her if she is in Atlanta. In September 2010, however, Lifetime declined to pick up the project to series.
In 2013, The CW announced there was a spin-off of their genre hit Supernatural in the works. The 20th episode of season nine titled "Bloodlines", served as a back-door pilot, revealed in January 2014 to have been titled Supernatural: Bloodlines. The series was set to explore the "clashing hunter and monster cultures in Chicago". The show was not picked up by the CW for the 2014-2015 season due to dismal overall reception by viewers.
The Gossip Girl episode "Valley Girls" was supposed to be a backdoor pilot for a prequel spin-off series starring Brittany Snow as a young Lily van der Woodsen, however the show was not picked up. "The Farm" was an episode of NBC's The Office that was supposed to act as a backdoor pilot for a spin-off series starring Rainn Wilson and focusing on his character, Dwight Schrute. Upon review, the spin-off was not picked up by NBC and the original version was never aired; instead it was reworked with additional material shot later, as the original version contained "certain aspects that were appropriate for a pilot of a new show".
A historically important venue for backdoor pilots has been the anthology series. They have variously been used as a place to show work still being actively considered for pickup, and as a venue for completed work already rejected by the network. With the decline of anthology series, backdoor pilots have increasingly been seen as episodes of existing series, one-off television films, and miniseries. As backdoor pilots have either failed to sell or are awaiting audience reception from its one-time broadcast, networks will not advertise them as pilots, only promoting them as a "special" or "movie". It is thus often unclear to initial viewers of backdoor pilots that they are seeing a pilot of any kind, unless they have been privy to knowledgeable media coverage of the piece.
In one extraordinary case, an unsold pilot was released as a theatrical film. A 1956 attempt to create a television vehicle for film and radio stars Lum and Abner was not picked up as a series, but the three pilot episodes produced as proof of concept for the series were strung together and released as a theatrical film titled Lum and Abner Abroad.
A put pilot is a pilot that the network has agreed to air either as a special or series. If the network does not air the pilot episode, the network will owe substantial monetary penalties to the studio. Generally, this guarantees that the pilot will be picked up by the network.
Unsold television pilots are pilots developed by a company that is unable to sell to a network for showing.
There have been numerous pilots for game shows that have been rejected by American television networks or syndicators:
Instead of a single pilot episode, an alternative is a test run, a small number of episodes that air as a short-run series with the potential to go into full production if successful. This is particularly common among shows that are intended to be stripped (airing five days a week).
In a 10/90 production model, a network broadcasts ten episodes of a new television program without ordering a pilot first. If the episodes achieve a predetermined ratings level, the network orders 90 more to bring the total to 100 episodes, immediately enough to rerun the show in syndication. Series that used the 10/90 model include Tyler Perry's House of Payne, Meet the Browns, For Better or Worse, Debmar-Mercury's Anger Management, and Are We There Yet?. Byron Allen's sitcoms followed a similar model, with Mr. Box Office and The First Family airing 26-episode first seasons with the intention of following them up with a full 104-episode order if successful; both series failed to reach the threshold Allen sought, though they remained in limited production (three to four new episodes a year, mixed in with the first season) for a few years afterward.
An earlier variant was the 13-episode pilot run; in the late 1980s and early 1990s, Disney Channel notably gave a 13-episode pilot order to two series it never picked up, but would go on to longer runs on other networks: Good Morning, Miss Bliss (which also had a traditional pilot on NBC and would be revived by that network as Saved by the Bell) and the Canadian drama Hillside (which would move to Nickelodeon, Disney Channel's primary rival, and air as Fifteen).
Talk shows occasionally use test runs. Metromedia and its successor Fox Corporation were particularly associated with using test runs for talk shows, with examples including The Wendy Williams Show,The Huckabee Show (a spin-off of Huckabee that aired for six weeks in summer 2010), the final version of The Jerry Lewis Show, and The Kilborn File, an unsuccessful comeback vehicle for Craig Kilborn.
A pilot episode is generally the first episode of a new show, shown to the heads of the studio to whom it is marketed.
The television industry uses the term differently from most viewers. Viewers frequently consider the first episode available for their viewing to be the pilot. They therefore assume that the first episode broadcast is also the episode that sold the series to the network. This is not always true, however, in part because of the factors mentioned above. For instance, the episode "Invasion of the Bane" was not a pilot for The Sarah Jane Adventures because the BBC had committed to the first series before seeing any filmed content - yet it is routinely referred to as a pilot. In the Canadian supernatural drama Lost Girl, the pilot that sold the series to Showcase, "Vexed", was used as the eighth episode of the first series. In the case of Firefly, the original pilot (Serenity) which was intended to serve as the series premiere was rejected by the network, and a new first episode, Train Job, was shot specifically for broadcast.
Sometimes, too, viewers will assign the word "pilot" to a work that represented the first appearances of characters and situations later employed by a series - even if the work was not initially intended as a pilot for the series. A good example of this is "Love and the Television Set" (later retitled "Love and the Happy Days" for syndication), an episode of Love, American Style that featured a version of the Cunningham family. It was in fact a failed pilot for the proposed 1972 series New Family in Town, but was recycled as a successful pilot for 1974's Happy Days. So firmly embedded is the notion of it as a Happy Days pilot, however, that even series actress Erin Moran viewed it as such, as well as its creator, Garry Marshall, since Happy Days itself did not have a separate pilot of its own.
On other occasions, the pilot is never broadcast on television at all. Viewers of Temple Houston, for example, would likely have considered "The Twisted Rope" its pilot because "The Man from Galveston" was only publicly exhibited in cinemas four months later. Even then, "The Man from Galveston" had an almost entirely different cast, and its main character was renamed to avoid confusion with the then-ongoing series.
