Jack Nicholson wrote and directed a basketball movie back in 1971, around the same time he was working on the Monkees Head. It's interesting.
And there's a Soderbergh movie available on Netflix that I have to watch. Maybe right now - High Flying Bird. Apparently there isn't any game action, but rather behind-the-scenes stuff with an agent.
I mentioned high flying bird in the other movie thread. I watched it last night and loved it. Interesting from a film making perspective in several ways, but also philosophically important when it comes to the business of sports and ownership of the means of production.
