Trivia: This film was originally intended to be the final chapter in the entire franchise, though since its release, it has been revealed that there have been talks for further films which would be released occasionally and allow the audiences to catch-up with the characters throughout their lives.
Trivia: While this film is the fourth main-series entry, it is technically the eighth film in the overall franchise, as four direct-to-video spin-off movies were released between the third film (2003's "American Wedding") and this film. Eugene Levy is the only actor to appear in all eight films, and co-star Chris Owen is the only other actor besides Levy to appear in both the theatrical films (including a cameo in this entry) and one of the spin-offs. (With a role in the first spin-off "American Pie presents: Band Camp.").
