A Guy Thing (2003)

Continuity mistake: When Jason Lee is driving the car over the humps in the road, Julia Stiles is in the passenger seat. In the shot before they take off Jason Lee is in the driving seat, when they show the shot of the car in mid air Julia Stiles is now in the driving seat, and in the shot as the car lands they are back in the right seats.

Other mistake: In the main titles, for casting, the name "Brennan Dufrense", is listed. It should read 'Brennan Dufresne'.

Audio problem: During the wedding part at the end the movie, when Paul announces he doesn't want to marry Kerry, Kerry looks at him and says, "Paul?" but you can see she is really saying, "What?" The voiceover comes in late as well. This is on the video version.

Trivia: The guy who plays 'Mister minister' also played Julia Stiles' dad in 10 Things I Hate About You, which also took place around Seattle. They give each other funny confused looks when she is leaving Jason Lee's apartment in the beginning of the movie.

Aunt Budge: I would kill for some diarrhea! I haven't had a bowel movement in 17 days.

Ken: So, Buck, are you a duffer?
Buck: Well, if you mean do I like playing with my balls, the answer's yes.

Dorothy: These are going to be our in-laws, so we really have to make sure that.
Buck: Honey, I'm a pants salesman. I think I know how to act around people.
