I had time to watch the bonus features, too. 4 deleted scenes, one of which was another surprise doublecross sequence (I guess they figured they had enough of them in the first half of the movie).
There was a nice 16 minute feature on "The Farm," the CIA training academy. Of course, all of that is top secret so they had to illustrate with clips from the film, so we don't really get to see what the real places are like. Still, interesting.
