Amy Smart was on the set of the movie Crank. She had the role of Chev’s girlfriend. She had a crazy sex scene with her co-star, played by Jason Statham. The plot said that Chev was poisoned and he needed to keep his adrenalin level high. So he and his girlfriend had to do a sexy act in front of hundreds of people in Chinatown. Amy said that filming for that was very funny because the extras would cheer everytime the director cut the film.
