28 weeks later (juan carlos fresnadillo, 2007)

Sequel to 28 Days Later delivers. It had been a long time since I saw this one, and even longer since I saw the original, but my memory is that they are equally impressive. The zombies are truly frightening; although 28 Days Later wasn't the first fast zombie movie, it's the one that got the most attention at the time, and if 28 Weeks Later lacks the surprise factor of its predessor, its relentless terror is still nearly unbearable. (And yes, I know they aren't technically zombies but rather victims of a virus.) The cast is terrific, full of people we think of now as stars who at the time were better described as "known": Robert Carlyle, Rose Byrne, Jeremy Renner, Idris Elba.
