Dead Snow is the best low-budget zombie flick seen in ages. A surprise audience hit at this year’s Sundance Film Festival, Dead Snow (in theaters 6/19) follows eight medical students who take to the mountains for their Easter vacation and come up against a gang of undead Nazis. Director Tommy Wirkola doesn’t shy away from gore (this film is not for the faint-of-stomach), and the whitewashed terrain adds another layer of creepiness.
