This official Transformers: Revenge of the Fallen behind-the-scenes video from Wal-Mart gives a closer look at the Audi R8 during the first day of shooting on the set. Also clearly visible is Michael Bay's massive douchebagitude. With all the hype surrounding the blatant product placement that is the Corvette Centennial Concept and the production-ready Chevy Volt we sometimes forget that the R8 is going to have some screen time too. Though it's not like Audi is showing off anything we haven't seen before. [via Transformers.MovieChronicles]
