It was the seventies Sam. Materialism was making a comeback. For poor kids this was a way out of the dead end they saw in their future, so many of them jumped at the chance for a corporate sponsor. Watch the documentary. These were real people. Most of the events happened in some fashion to the team members, but to make it a more cohesive story, Peralta put it into one year and focused on the three main characters for the movie. Put the Dogtown and Z-boys documentary on and watch for how well they all match the mannerisms of the real people they are portraying. They also had to be convincing skating and in some scenes surfing. Watch the movie again with Peralta and Alva's commentary running and you will see and hear how close they got it to the real life these guys had. How can you say Emile Hirsch is one dimensional? John Robinson does most of his own skating. Peralta himself doubles for the multiple 360s in the Delmar contest scene. The real Alva does some as well. I've never even skated, but I lived through the seventies and I thought it was like stepping back into the past. Very convincing. The only thing I would have done differently would be to develop Wentzle's character more-he is a hoot in the documentary.
