There's a pretty good free running video on Google here. I'd seen some other videos, but this is one of the better (ignoring the dorky 30 seconds or so about a minute into it where there is no action, just camera movement).
Watching this definitely reminds me of some of Jackie Chan's moves in his movies, and my immediate conclusion was that big-budget movies are probably going to start using more and more free running in their chase scenes.
Of course a little bit of research led to finding parkour - the name for the original physical discipline from which free running has grown. Parkour is the minimalist approach to getting through obstacles as efficiently as possible, whereas free running is more artistic (free-form) that doesn't necessarily care about efficiency.
And, I also found out some of it is going to be used in the new James Bond film, Casino Royale. cool.
