I've read on a few DVD sites that MGM should have called this the "Oh My Goooooood!" edition and put the Best Worst Movie Ever as the main extra on it.
It's probably common knowledge here, but Darren Ewing (Arnold) is active on IMDB's message boards and he has said that he tried to deliver that line normally and the director kept cutting and telling him to say it the way it ends up in the movie. So eventually he shrugged and delivered it terribly, as directed.
Anybody else see Jack Brooks:Monster Slayer? That would have made a good Troll 3. Gotta love Robert Englund.
