Joseph Gordon-Levitt is a fine actor. I've been impressed by the guy since Brick, mostly because as an actor, he tells real stories in a very real way. Yet there is always something in his performance that alludes to the unreal, as in holy-shit-this-guy-is-so-good-it's-unreal. He understands when to go big, and when to make something so small that as an audience, we can see a lifetime unfold in one small gesture.
Plus, he's also very easy on the eyes. Swoon.
I loved his new flick, 500 Days of Summer. Go check it out!
