I did a little poking around to see what the deal was on the movie. Right now it appears that there might be some limited movie theater release, but there were no specifics.
I would look for it to show up on DVD sometime this summer??
BTW - It was EXCELLENT! Once you get started watching it just draws you right in. It is a documentary about Audi for the run up to the 2008 race at Le Mans. This time Audi was coming in as the underdog after Peugeot won in 2007. Great racing footage, great interviews with crew and drivers, and some awesome video.
