When David Arquette did a panel for this film at the 2006 San Diego Comic-Con International, the footage he wanted to show was missing. He offered a reward of a car that was used in the movie for the return of the footage.
What are the differences between the R-Rated and Unrated Version?
A
In the USA, the movie was only released in a slightly longer Unrated version, while European countries (such as the UK or Germany) had to live with the shorter R-Rated version. The Unrated version is a little different from the R-Rated version and features four alternate scenes and two additional scenes. A detailed comparison between both versions with pictures can be found here.
