I just saw Killer Elite
today. It was better than I expected. I mostly saw it because Jason Statham is in it, and he does solid, entertaining action flicks, but I hadn't realized that Killer Elite is (at least partially) based on a true story. The movie ended up having some political twists and turns I didn't see coming, which was nice. I'd definitely say you should give it a look if you don't mind the violence, or enjoy it, as my case is.
