The film was originally submitted to the BBFC on 30th June 2006, where it was passed with a 15 certificate. However, on 30th November 2006 the film was submitted again as a "re-edited" international version, with "changes made to reels 2, 3 and 5". This new version runs 16 seconds longer and was awarded a lower 12A certificate. The BBFC's website does not list the specific changes made.
Was originally rated R by the MPAA for "some violence" but was later edited down to a PG-13 rating for "some intense sequences of violent action, some sensuality and language."
