NEW YORK, Nov 26: Gay cowboy drama “Brokeback Mountain” may have been considered a risky film to make, but director Ang Lee said his new movie, “Life of Pi,” a 3D exploration of faith about a boy stranded on a boat with a Bengal tiger, is his riskiest yet. The film, which was released in U.S. theaters this week, is adapted from Yann Martel’s best-selling novel of the same name and was once considered impossible to make. (agencies)
