I think it would be cool if a bunch of pros were thrown into a random park/setup with a filmer and were given a day to get footage for an edit. After that day, they are given another day to edit the movie and then they realease it and the judges vote on the best edit.
So in other words, basically realski, but they are given the same park to work with. It'd probably have to be a pretty big setup too
If this idea has already been thrown out there then stop me now.
