Author! Author!

According to 'Coming Attractions' magazine, "The idea for the film emerged in a conversation between two lifelong friends, Israel Horovitz, writer of the screenplay, and Irwin Winkler, the producer. During their discussion of married life, they found themselves asking, 'What happens to a man when his wife runs off and leaves him with the children? Kramer vs. Kramer (1979) was one answer to this question; Author! Author! (1982) is Mr. Horowitz's answer, and it has special personal significance for him because of his own experience as a divorced father with primary responsibility for two of his three children".

When Ivan and Alice meet at the plaza, Alice has 3 glasses of champagne and 3 aspirin in front of her, which she sips from and swallows during the conversation. She takes more than 3 aspirin, although 3 are clearly shown. And the liquid levels in the champagne glasses change from shot to shot.

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.
