Jon Turteltaub's blockbuster action-horror film was filmed in China and New Zealand. A deep-sea submarine is attacked by a megalodon: a 75-foot living fossil and the largest shark to ever exist. To rescue the crew from this unexpected prehistoric uber-predator, a Chinese oceanographer (Winston Chao) and his daughter (Li Bingbing) enlist the help of a veteran deep-sea rescue diver (Jason Statham).
