Ever since the idea of turning Yann Martel’s award-winning book Life Of Pi into a movie was first mooted, people have wondered how on Earth you’d turn a book that’s largely about a boy and a tiger trapped out at sea into a film. However Ang Lee has managed it, and at its film festival screenings it’s been getting some good reviews. Now a featurette has arrived looking at the challenge the filmmakers faced, and how even Martel himself thought his book was unfilmable. Life Of Pi hits UK cinemas on December 20th in 2D and 3D.
