Inside Man

Wowsa.  I think this type of movie is my favorite, where it is absolutely completely unpredictable.  Ok, so he kept saying he'd walk right out the front door, but still.  It had a wonderful ending, and when I say that I don't necessarily mean a happy one, but just one written and acted out well enough that satisfies the movie in itself.  Definitely watch it or put it on your list to watch, and I'll go on and watch some more in the meantime.
