Actress Dyan Cannon was initially offered the part of Gloria Travalian but Cannon turned down the role because she felt the character was too "bitchy" and had played a "bitch" before. Later on, Cannon was given the role of Alice Detroit, and thoroughly enjoyed making this film and likened the experience to like "being on a cruise". And Tuesday Weld was cast as Gloria.

In the theater scene immediately following meeting with Alice, Ivan sports an entirely new hair do. The play's director acknowledges it. Then the very next scene has Ivan exiting the subway station with his old hair do.

The 2005 Region 2 DVD, and the 2007 Region 1 DVD, which were both released by Fox Video, contains the following changes: Alternate opening title credits (white titles over black background). No title credit to both the song 'Coming Home To You' and the song's vocalist and writers (Michael Franks, Alan and Marilyn Bergman). Johnny Mandel credited as the film's composer. Film ending with Ivan and the kids at the newstand. Previous video releases by 20th Century Fox Video, CBS/Fox Video, and Fox Video contains the opening credits in white text playing over the NYC skyline backdrop to the set in the playhouse, a title credit to both the song Coming Home To You, and its vocalist and writers (Michael Franks, Alan and Marilyn Bergman), David Grusin credited as the film's composer, and the film ending with the kids celebrating Ivan's success by pouring champagne and cake on him while he is in bed. David Grusin was hired to rescore Johnny Mandel's original score. David Grusin's score is heard in the final film.
