    Life of Pi(少年派的奇幻河流)is to become the first 3D film to open the New York film festival. This year's New York film festival runs from September 28 to October 14.

    The director of this movie is Ang Lee, an American Chinese. The movie speaks of the relationship between humans and nature. Indian boy Priscine Patel is troubled by his first name. And his classmates laugh at him. So he decides to change his name to "Pi".

    Pi's father has a zoo and he decides to move to Canada. The family, together with all the zoo animals, sail across the pacific(太平洋). One day, a huge storm hits the ship. The next morning, Pi finds his family have sunk(沉没)with the ship. He is the only person still alive. He finds himself on a lifeboat with several animals, one of which is a tiger called Richard Parker. Soon, all the animals are killed by the tiger. And Pi is left alone with the tiger.

    As the tiger becomes hungry, Pi starts to fish to feed him. If not, he himself will become the food. The boy and the tiger develop an amazing relationship on the sea. Although he feels hopeless, Pi never gives up. After 227 days, the lifeboat finally lands on a beach in Mexico, but Richard Parker runs away into the forest. The ship company finds Pi and asks him what happened. Pi tells them about Richard Parker, but the company doesn't believe him. Pi then tells another story in which is no tiger.

    Is there really another story? If so, which one is true? Maybe you will have your answer after watching the Life of Pi.
