is a 1953 British film produced by The Square Ring Michael Relph, directed by Basil Dearden and made at Ealing Studios. It stars Jack Warner, Robert Beatty and Bill Owen. The film, based on a stage play by  Ralph Peterson,  centres on one night at a fairly seedy boxing venue and tells the different stories of the various fighters and spectators.
Five stories that take place mainly in the locker room prior to and after various bouts during a single evening at a cheap boxing stadium: an ex champion, Docker Starkie, trying to make a comeback; Eddie Burke, a new boxer on the way up; Harry Coombes, a future champion; Rick Martell, a crooked fighter planning to throw a fight; Sailor Johnson, a punch drunk 'has-been'; and Rowdie Rawlings, a black boxer. Danny Felton is the dressing room attendant who has seen fighters come and go.
Original 1952 Play
The film was based on a 1952 play with the same name by Sydney-born radio writer
Ralph Peterson who arrived in London only the year before. 
He wrote it over a three-month period. Peterson was inspired by material he had learned from writing the 1950 radio play
Come Out Fighting, set in the world of boxing.  
He sent the play to
Anthony Quayle, who he had met in Sydney, who agreed to put it on.  
Film rights were bought by
Michael Balcon at Ealing and John Mills was announced as star, with Basil Dearden to direct and Michael Relph to produce. 
Eventually Mills dropped out and was replaced by Canadian actor Robert Beatty.
He had no boxing experience so he trained for two weeks in preparation for the role.  
Critical reception was mixed. One review called the film "uneven", accusing it of "veering between comedy and tragedy".
Peterson adapted the play into a 1954 novel.
