5. '28 Days Later' (2002)
If you're up for hardcore zombie scares, look no further than this killer-thriller from Slumdog Millionaire Oscar winner Danny Boyle. Twenty-eight days after a virus decimates London, newly zombified citizens pop up to take you down like stealth bombers. If one of them even drools on you, you're a raging jungle beast in 20 seconds. Survivors, led by Cillian Murphy and Naomie Harris, try to escape. They wish. No way you can forget the zombie uprising in a church where crosses just don't do the trick. Boyle and screenwriter Alex Garland keep things scary and visionary. A sequel, 28 Weeks Later, followed in 2007. It has its moments. But this is the real deal.
