Fuck yes.... everyone needs to own the DVD of this movie because of all the neat shit it comes with.

I don't recommend navigating the DVD menu while high. The first night I owned the movie I got really stoned and spent TWO HOURS watching the special features because for the life of me I couldn't find the actual movie.
The trailer doesn't lie. People in gorilla suits would come out during the climatic scene and "abduct" a female who is also in on the gimmick.
