Alternate versions

The DVD contains the original ending, set in the school's gym pool. The producers and the director decided to shoot a different ending because the original ending was very different in its style of humour and horror and they thought it didn't fit into the film.

The workprint version is similar to the theatrical cut but has some different shots and has the original ending.

The TV version seen on Sci-fi has alternate takes of scenes with profanity, instead of awkward overdubbing. Most notably the scene in Pnub's bedroom where "I hate that fuckin' show" is missing the f-word and "Jerking off in the milkshake maker" is changed to "Spitting in the milkshake maker"

Besides the profanity noted above, all scenes of drug use have been taken out on TV too. This makes the ending very odd (Anton mysteriously has smoke in his mouth but we never see where it came from). Some blood/gore has been taken out, and some nudity has been taken out too.
