The only thing I've ever been somewhat irked with Brad Pitt over was when I was at Laguna in '05 and traffic (foot and mobile) was halted near the front straight so that his helicopter could land and he could get to the track on time for the race to start. But...he cared enough to be at the first United States Grand Prix in 11 years and I can't fault him for that.
Need more like him doing things to bring the sport into the eye of the general public.
