READ NO FURTHER- IF YOU HAVE NOT SEEN THE MOVIE AND DO NOT WANT TO KNOW WHAT HAPPENS!!!
The first "chase" scene was outstanding. The guys who jump around on buildings like that are called "free runners", and they do some amazing stuff, as seen in the film. I'm glad they put this in, instead of some wire flying crap. It made for some of the best stunt work I have seen for some time.
Can't wait to see some kind of "making of".
