It's things like this that make me take a deep breath and hope for the best and expect the worst...If the movie is a big hit a few things could happen
A.) like acewall said, it will be easier for us all to pick up girls, which i'm sure we can all agree is a positive thing
B.) every conversation with a person (who's never really seen parkour) after that movie will go as follows. (this is if the movie portrays parkour in the wrong light)
Passerby "Hey, that's neat, what are you doing?"
Traceur "Parkour..."
Passerby "Oh, like in that movie there with the bankrobbers....I bet cops could never catch you"
Traceur*Frown* "Sort of, but not really, we don't train to steal stuff, we train to...."
Passerby "Yeah, ok, whatever see ya"
Traceur*heavy sigh, and goes back to training*
[end skit]
C.)a bunch of kids will see it, not bother finding out the proper ways to do parkour, and end up going and hurting themselves doing things the wrong way
D.) a bunch of kids see it, go online, find forums like this one, learn how to do things the right way, and the parkour community benefits from the publicity, as long as you don't mind a little media attention.
A and D are my personal favorites of the scenarios i've composed
