Bradley Cooper had car trouble on the set of “The Hangover.” He told VF.com that seven different Mercedes convertibles were used in the movie, but one was stolen from the Las Vegas set. “Of course, they found it the next day, because you couldn’t miss the car. Not only that, the guy who stole it also robbed a bank. So they found him with that car, and, like, an old cartoon safe in the back seat. With the top down.” Cooper said “Hangover” producer/director Todd Phillips gave the entire cast Vespas as gifts after finishing the sequel, “The Hangover Part II.” “I thought, a Vespa? What the heck kind of gift is that? But I tell you, I cannot stop riding that Vespa.”
