Narm: Characters use the word "motherfucker" a few times. To preserve the film's PG-13 rating, they're always cut short so they say "motherf------". It's noticable. Especially when the word forms part of the chorus of a background song.
Blame Executive Meddling for that one, this film was originally slated for an R rating, but after 9/11 the studio execs were under the impression that audiences didn't want to see violent action movies anymore, so this film ended up being toned down.
