I had been really looking forward to buying this DVD but was disappointed to find that this version of the movie is not the same as the one shown at the Toronto International Film Festival in 2007. It has been pretty heavily edited. Granted, some of the cuts were warranted; there were too many similar scenes with the Sheriff originally, and the homophobic gags have thankfully been removed.
However, I did miss Akira's scenes and the Mayor's scenes. Even though they were not essential to the plot, they did help to create sympathy and explain the motivations of the main characters. Let's face it, this film is not really about the plot anyway; it's about the little details and how much fun you have along the way.
Finally, a word of advice: Be sure to watch with the subtitles on. The actors speak in English, but not without an accent. Even in the theatre it was shown with subtitles.
