When Tom and Eli come out of the theater, a poster for The Opposite of Sex (1998) is visible by its entrance. Actors Lisa Kudrow and Christina Ricci starred in that film, Dan Bucatinsky appeared in it, and executive producer Don Roos wrote and directed it.
Richard Ruccolo stated that he's "honored" and "humbled" to have had the opportunity to work on this movie. He further noted that "All Over the Guy" "has and always will be one of the highlights" of his life.
In the original screenplay not only Jackie says, "I know gay men, I practically invented them", but she adds further: "I have ex-boyfriends to prove it".
The movie's entire budget was $500,000.
The name of the producer of the movie, Juan Mas, is used in the police report that Tom reads to Eli.
