An Extended Version of the movie, which features about 38:47 min. new material, was released in the US. The US DVD features the correct aspect ratio (2.35:1), good video and audio quality and useful goodies. Most interesting is the original making-of.
The downside of the Extended Version is, in my opinion, that there are only a few meaningful new scenes and the movie is being prolonged a lot. Most of the new scenes just emphasize the trashy character of the movie. Some of the new dialog lines are really stupid and the extended death scene of Henry Fonda makes the Extended Version really enjoyable.
