You must watch this brilliant recut trailer!
I know, I know, The Hangover is already sort of a horror movie to us movie snobs. But this fake trailer takes it to the next level, recasting the film as a straight up horror movie with Alan as a deranged maniac wreaking havoc in Vegas. The color is desaturated, the music is changed, and the editing is precise and, frankly, scary!
Richard W. Scott created this trailer as part of his undergrad dissertation, he explains, "as part of an experimental investigation into the power of post-production techniques on a movie's genre." Result: you can really do some amazing stuff with editing.
