Simon Pegg and Nick Frost in Hot FuzzHOT FUZZ

Not that many of you have seen them, but in between Rodriguez's and Tarantino's Grindhouse offerings, there are faux "coming attractions" for forthcoming trash flicks, one of which is directed by Edgar Wright. The trailer in question is for a slasher film called Don't, and in about 90 seconds of screen time, Wright - director/co-writer of the peerless zombie comedy Shaun of the Dead and the new action spoof Hot Fuzz - manages to lampoon (and celebrate) just about every cliché in the horror-preview bible: the insidiously throaty voice-over announcer; the shock edits, punctuated by screams; the sudden bursts of outré violence. It's a brilliant, savage parody, yet the trailer's ultimate joke is that it's legitimately effective; you find yourself actually wanting to see Don't. Wright tweaks genre previews and outdoes them in the same breath.
