Crazy Legs Conti:

To mark the premiere on Tuesday of a film about his life as a competitive eater, Crazy Legs Conti is trying to eat his way out of a telephone booth-size structure filled with popcorn.

Conti, 33, donned a diving mask and snorkel on Tuesday inside the lobby of the Manhattan movie theater that will show the film and lowered himself into a "popcorn sarcophagus," a wooden, windowed structure, to begin munching.

He vowed to eat his way through the 50 cubic feet of salted, buttered popcorn in about eight hours, in time for the movie's premiere on Tuesday evening.
