Disowned Adaptation: Heywood Gould, the author of the novel, was not pleased with the movie version.
Missing Trailer Scene: The film's theatrical trailer included part of an extended version of Brian and Doug's final meeting on Doug's yacht. This darker version had Doug claiming he had made a move on Jordan, which sets Brian off into a rage. Doug exclaims "I don't have any friends!" to which Brian replies "As of right now, that is for sure!" Had this scene been in the movie, it would have better explained why Brian is initially open to sleeping with Kerry, and Doug's suicide.
Real-Life Relative: Elisabeth Shue's brother Andrew Shue can be seen briefly in the background during the wedding reception scene.

Write What You Know: Screenwriter Heywood Gould wrote the book and the film based on his experiences as a bartender in the late 1970's and early 1980's, a position he took as a struggling writer.
Write Who You Know: Heywood Gould says the lead character "is a composite of a lot of people I met, including myself in those days. I was in my late 30s, and I was drinking pretty good, and I was starting to feel like I was missing the boat. The character in the book is an older guy who has been around and starting to feel that he's pretty washed-up."
