Woody Allen once famously said the following quotes about sex: (1) "It's the most fun I've ever had without laughing" (2) "Having sex is like playing bridge. If you don't have a good partner, you'd better have a good hand" and (3) "I'm a practicing heterosexual, although bisexuality immediately doubles your chances for a date on Saturday night". Moreover, Allen once said that he included in this movie "every funny idea I've ever had about sex, including several that led to my own divorce".
According to the book "Woody Allen" by John Baxter, Gene Wilder once said of the making of this movie: "It was like walking on a Bergman set: people talking in whispers, serious looks on Woody's face. He communicates through silence".
A segment that was filmed but eventually cut out of the film was "What Makes a Man a Homosexual?" The sequence had Woody Allen as a common spider and Louise Lasser playing a black widow. After a mating dance on the black widow's web, the spiders make love and the black widow eats the common spider. Allen cut the sequence as he was unable to find a suitable ending for it. Apparently, some production stills from it have been used for promotional materials for the film even DVD covers.
The "Everything You Always Wanted to Know About Sex * But Were Afraid to Ask" title, which is, at its full length, with thirteen words, is the longest ever title for a Woody Allen feature film. It's still the longest too when one counts its shorter eight word version "Everything You Always Wanted to Know About Sex". Allen's second longest feature film title is You Will Meet a Tall Dark Stranger (2010).
The number of vignettes in the film was seven. The titles of the seven sections are each derived from chapter titles from David Reuben's source book. Moreover, all the film's segment titles and all the book's chapter titles, are all formed as questions.
The only ever official filmed adaptation of another person's previously written work by Woody Allen though a number of Allen's films have been inspired and influence by various films and novels. However, though little is taken from Dr. David Reuben's source book 'Everything You Always Wanted to Know About Sex (But Were Afraid to Ask)', the picture hardly counts as an adaptation.
Dr. David Reuben, the author of the source book 'Everything You Always Wanted to Know About Sex (But Were Afraid to Ask)', did not like the film, and in an interview with the L.A. Herald-Examiner, said: "I didn't enjoy the movie because it impressed me as a sexual tragedy. Every episode in the picture was a chronicle of sexual failure, which was the converse of everything in the book".
First of two anthology / omnibus / segment / portmanteau films made by Woody Allen. The second, New York Stories (1989), would be Allen's second compilation film after this movie, a gap of around seventeen years. In the latter though, Allen only wrote and directed one vignette, whereas in this film, Allen worked on all of its segments.
Actor Elliott Gould and producer Jack Brodsky were the first people to option David Reuben's book, but opted to sell it to United Artists once they determined that the text was too hard to film. The TCMDb suggests that the reason was due to when "Gould and Brodsky dissolved their partnership".
Showbusiness trade paper Variety said of this film that it "borrows only the title [from Dr. David Reuben's Everything You Always Wanted to Know About Sex (But Were Afraid to Ask) book] and some . . . questions [the segment titles]".
