I like the fact that they didn't shy away from genre or exploitation films, and that they recognized that a trailer can be fantastic even if the movie is... less-than-fantastic. (I love Stephen King but Maximum Overdrive is a pretty awful movie. Righteous trailer, though, as evidenced by its inclusion on this list.)
Those trailers for The Shining and Alien are real head-benders, aren't they? The trailer for Corruption looks delightfully insane, I wish the movie was on DVD.
