On paper, Ang Lee’s ‘Life of Pi’ sounds like an Oscar-contender. The ‘Brokeback Mountain’ director has Academy recognition (having won the Oscar for his cowboy drama). And he’s tackling a best-selling, prize-winning novel with a plot that presents all sorts of visual and narrative challenges. If he can overcome them, Lee and his adaptation are sure to be in the Oscar conversation. All that’s left is for audiences to see the movie, and this first trailer is going to help sell the goods.
