The Scott Pilgrim film adaptation did not have a straightforward production history. It was written and filmed while the final volume of the original comic book series, Scott Pilgrim’s Finest Hour, had not yet been released; and a substantial amount of the movie had to be cut or reshot due to the MPAA® rating rules changing during production. These changes meant that, for example, characters would not be allowed to smoke on-screen (leading to a much shorter, reshot first date, in which there is unfortunately less chemistry between the leads), and certain words had to be bleeped out or scenes cut entirely to remove them. Many others were simply cut for time. Scott Pilgrim vs. the Editor incorporates many of these deleted or altered scenes back into the film, as well as the [adult swim] animated shorts. Extended and additional songs and gags have also been seamlessly integrated into the film, including finished visual effects, colour grading and matching, and an enhanced audio mix.
