"Best Worst Movie"
I watched this last night, it was pretty funny. It's a documentary about "Troll 2," the movie which imdb.com has listed as the worst movie ever.
It was made in the late seventies/early eighties, and it has nothing to do with "Troll 1."
But the film has become a cult classic, and the documentary goes and finds all the actors that were in it, and then shows some or all of the actors going to midnight screenings of the movie, where they all get to see people laughing and applauding and cheering for the movie. It's pretty funny, people are asking the actors to say lines from the movies, and while it's running it's kind of like Rocky Horror.
I recommend this documentary to anyone who's ever loved a "bad movie."
