Alec Baldwin risked serious injury when he accidentally fractured a former felon's thumb during a game of football on the set of THE DEPARTED. The movie star's castmates and crew members refused to take Baldwin seriously when he turned up for the game in a suit and tie - but he won them over with one fiery throw. However, one of co-star Mark Wahlberg's friends, who caught the pass, wasn't impressed after he was left injured - and Wahlberg had to step in to prevent a nasty altercation. Wahlberg tells Rolling Stone magazine, "He threw a pass to my buddy John Shea and fractured his thumb. "This guy, he's a boxer from Boston, and he did 12 years in federal prison. John was a little upset about his thumb, but I told him it was all good."
