Below is a trailer for the film 500 Days of Summer reimagined as a "thriller," i.e. a film in which Joseph Gordon-Levitt's character is recast as a nefarious stalker who targets Zooey Deschanel's character after she dumps him. What's interesting about it, of course, is that the scenes aren't really recut to look like a totally different movie; it's just got a creepy score instead of some charming indie single laid over it. And that makes it a pretty awesome commentary on the oft-discussed stalking-as-courtship trope, which features centrally in so many romantic comedy films.
[A transcript really wouldn't be of any use here, since the video is almost entirely free of dialogue. The paraphrase is as above: Scenes of a romance, a break-up, and the commencement of stalking by a profoundly unhappy jilted dude.]
