Actor Gerard Butler was involved in a surfing accident Sunday in California. The actor, 42, was filming the surfing movie Of Men and Mavericks when he was pulled underwater and dragged over a rocky reef by waves. Butler was held down for two waves. The scenes were shot at the surfing spot Mavericks, which is known providing conditions for big-wave surfing during the winter with waves reaching up to 80 feet. Over the years, several surfers have died there as well. Among them was Hawaiian surfer Sion Milosky, who died in March after a wave he was riding collapsed on him and held him under. Butler was rescued by a safety patrolman and taken to Stanford Medical Center in a dazed condition. However, he had no life-threatening injuries and was released soon afterward. "[Butler] had that 100-yard stare that surfers get after a two-wave hold-down or near-death experience," said a reporter of ESPN. Although Butler is not an experience surfer, he reportedly did nothing too dangerous. "Everything he was doing was within reason," the patrolman said. "We took like four to five pretty big waves on the head. Basically, there's nothing you can do." The actor has yet to issue a statement on the incident.
