The new Bruce McDonald movie, Pontypool. Fucking intense and an amazing twist on zombie movies.
Timecrimes, a Spanish time travel movie. Really cool concept. Plus the one character looks like Darkman, and the female lead has perfect tits.
Both of these movies only have a few actors, and a few locations, but they manage to keep you completely engaged. Got me stoked on how a great script is so much more important than a big budget/famous actors/special effects/etc.
