I went to see the Bourne Ultimatum this afternoon. If you liked the first two you will like this one. It was done very well. One error that I did see was in one scene he is shown with a Sig Pro. The camera even does a close enough shot to see the Sig Pro printed on the grip panel as the weapon was tucked into his waistband. Later, he is shown with a Glock, but this is just after mixes up with some cops, and I thought that he had possibly grabbed one of theirs. In a subsequent scene, he was holding a Glock on a guy. He then raises the Glock towards the other guy and the sound of a hammer cocking is heard. A minute later, he is once again holding a Sig.
