3. Eli Roth Turns Up As One Of Many Severed Heads - Hostel: Part II (2007)
Eli Roth has his fair share of detractors, many of whom will jump at the first chance to call him a talentless hack and criticize his "limited vision and scope." As far as I'm concerned, the guy is a great B-movie director, and knows exactly what he's doing and how to make solid, pulpy horror movies. Still, if you happen to be one of the Roth haters, you might want to check out
Hostel: Part II, in which the director makes a cameo as a severed head. Feel better now?
