WES CRAVEN AS FRED THE JANITOR (UNCREDITED) IN SCREAM (1996)
People seem to love this one—the Freddy Krueger creator popping up as a janitor. And yeah, we guess we kinda get it; it has some nostalgia factor going for it. Still, it's pretty obvious and predictable. If we were directing Scream we would have went completely wildcard on that ass and threw in a cameo from Maximillian, the vampire from Craven's awful Vampire in Brooklyn, but we digress.
In all seriousness, we much prefer the Linda Blair cameo as a news reporter. It's much more subtle, clever, skillfully done, and a tad-bit ironic.
