"I tried to make it as much about humanity and dignity, in a story that has been dragged through the media," says Kirsten, 36, who was nominated for an Oscar for co-writing the semi-autobiographical film In America. That was, kind of, my goal. We haven't started casting yet. Win my brother's role? Easy as Pi Many actors find that their success causes jealousy among their brothers and sisters. For Suraj Sharma, who won the leading role in Life of Pi, stardom will be even more awkward. The unknown Indian actor tells Mandrake that he won the part in the film adaptation of Yann Martel's Booker Prize-winning novel that his sibling had coveted. "It was my brother's audition," the 17-year-old son of two mathematicians says at the film's premiere at the Empire Leicester Square, in London. I just went along with him for moral support and I ended up getting the part. I wasn't going there to audition. I just got lucky - very, very lucky, I think. In the film, which goes on general release next week, Sharma plays Pi Patel, the son of a zoo-keeper shipwrecked with a zebra, a hyena, an orang-utan and a Bengal tiger. "My brother is a far better actor than me," he insists. I think it was just something to do with [my] being more age-appropriate for the part or something.
