Carol Lipton, played by Diane Keaton, claims to hate wearing a tie with a skirt. She made that look famous playing Annie Hall in Annie Hall (1977).
Nota caratteristica regista: [Woody Allen] [writer] Marcia Fox is a writer.
Woody Allen was inspired in part by The Thin Man (1934) series of movies, modeling his main characters after Nick and Nora Charles.
Woody Allen planned to make his earlier film Annie Hall (1977) a murder mystery, but cut that subplot out and used the initial murder mystery for this movie.
"Manhattan Murder Mystery" was actually the generic working title during production - Allen films usually have generic titles during production like "Woody Allen Fall Project" - but since no new title could be thought of, Woody Allen decided to leave that as the title.
The "man in Indiana" who chopped up six people and ate them the Liptons discuss is obviously a reference to Jeffrey Dahmer, with the first New York Post article about him in their paper.
The only one of the many movies they made together, in which Woody Allen and Diane Keaton’s characters have a child together.
In the scene when Diane Keaton's character sees her "dead" neighbor riding a bus, you can read VERTIGO as bus advertisement. It's one of the many references to Hitchcock's film that appear in the movie.
When Larry and Carol go to the theater, the play they are seeing is “Guys and Dolls”.
