12. ‘Rec’ (2007)
Memorable quote: “The police won’t let us leave and are giving us no explanations.”
Scare factor: This instant classic has some serious grip-your-armrests and hold-your-breath scares in it (and it’s better than its American remake, “Quarantine”). If you live in a multi-unit apartment building, you’ll be planning your escape routes after watching this film. And go ahead, try maintaining complete silence in the grip of total panic. It’s not so easy, is it?
