Actor Johnny Depp helped a fan who was being crushed in the crowd at last night's Pirates Of The Caribbean: DEAD MAN'S CHEST premiere in London. The Leicester Square extravaganza attracted thousands of fans hoping to get a glimpse of the movie's stars and Depp was quick to react when the crowd surged forward, trapping a young girl at the front against security barriers. Reprising his role as JACK SPARROW, Depp attended the premiere with co-stars Keira Knightley and Orlando Bloom and spent an hour-and-a-half signing autographs and posing for pictures with fans.
