After the Theatrical Version had a crisp running time of just 85 minutes, Warner Brothers submitted an Extended Cut to the MPAA that was also rated R but runs 10 minutes longer. It's undoubtful that you get the better film with this version. If you can accept that the film connects one comedic exaggeration to the next, the Extended Cut will provide you with much more of that (which is really funny in some scenes, e.g. Ferell's night journey). This version will not be available on DVD but the Blu-ray contains both cuts of the movie.
