Richard Benjamin previously directed a similar film, My Favorite Year (1982). Both films feature a young comedy writer on a 1950's TV show that is based on Your Show of Shows (1950), and stars a Sid Caesar-like comedian. Mark Linn-Baker, who plays one of the writers in "Laughter," played the young writer in My Favorite Year (1982), which was produced (uncredited) by Mel Brooks, a fellow writer with Neil Simon on Caesar's 1950's TV show Your Show of Shows (1950).
"The Max Prince Show" is based on Your Show of Shows (1950). It was broadcast between 1950 and 1954.
One of three Neil Simon written films which actor-producer-director Richard Benjamin has worked on. Benjamin co-starred in The Sunshine Boys (1975) and directed The Goodbye Girl (2004) TV remake (also a producer) and the tele-movie Laughter on the 23rd Floor (2001).
The number 23 was chosen as the floor level in the title for the source play because, according to Neil Simon, script sessions for the original 1950s Your Show of Shows (1950) were held either on the 11th or 12th floor of the NBC-TV building. Add them together and one gets 23.
