20. Mulberry Street (2006)
Director: Jim Mickle
Sticklers for accuracy might squawk at the inclusion of indie director Jim Mickle's Mulberry Street on this countdown, since the "zombies" in question are actually Manhattanites infected by some kind of mutated rodent virus, which turns them into man-sized rats. But anyone who's ever seen a George A. Romero film can spot an unabashed Romero homage when they see one, and Mulberry Street is most certainly that.
It's also a lean, mean, economically made roller coaster ride that features a formidable antihero (screenwriter-actor Nick Damici), impressive makeup effects, and several sequences of claustrophobic intensity set inside an atmospheric apartment building.
