Adapted by John Paxton from the 1965 novel of the same name by Katharine Topkins, the film tells the story of an elderly man who leaves his family rather than go into a nursing home, and strikes up a friendship with a pregnant teenage girl. It was Lemmon's only film behind the camera and partnered him with friend and frequent co-star Matthau.
Portions of the film were shot and set in Palm Springs, California.
The film earned rentals of $3.6 million in North America and $1.4 million in other countries. It recorded an overall profit of $330,000.
The film was nominated for Academy Awards for Best Actor in a Leading Role (Walter Matthau), Best Film Editing (Ralph E. Winters), Best Music, Song (for Marvin Hamlisch and Johnny Mercer for "Life Is What You Make It"), and Best Sound (Richard Portman and Jack Solomon).
Kotch was released in a Region 1 DVD by Fox Video on July 6, 2004.
