Gurinder Chadha wants Saif to play Nehru in her next!

Britain-based Indian filmmaker Gurinder Chadha sports a new look and is ready to wear the director's hat again. She'll soon begin filming a movie on partition, to be shot in Delhi and Jodhpur, and is keen to rope in Bollywood star Saif Ali Khan as Jawaharlal Nehru in it Chadha, who has
lost 25 kg, has already spoken to Naseeruddin Shah to play Muhammad Ali Jinnah in the film -- and he's game.

"This is my biggest challenge to date. I've been working on my partition film for some time now. The central character is Lord Mountbatten. The movie is set in January 1947 when Mountbatten was asked to oversee India and the movie ends in August 1947, so it's a brief time span.

"But (it is) a huge canvas requiring tonnes and tonnes of research and scores of characters. I've spoken to some people including Naseer and Saif. Nehru's role is a cameo, so I wonder if Saif would be willing to do it," she said on phone from London.

She has been working on the partition film while changing nappies and feeding the babies. She plans to roll it on floors in October.

The film's central figure would be Lord Mountbatten, and either of the two Hollywood biggies -- Colin Firth or Michael Fassbender - will step in to play the role.

The "Bend It Like Beckham" and "Bride and Prejudice" filmmaker has already locked locations for the shooting.

"I've already acquired the necessary permission to shoot everywhere in India including Rashtrapati Bhavan. So I am all set. I don't have to shoot in Pakistan at all. This would be my ultimate dream project and I can't wait for it to take off," she added.

But she has to wait until October because an astrologer has advised her so.

"The wife of the author of the book, on which my partition film is based, is heavily into astrology. She says October is a good time to start," she said.

For now, she is looking forward to running between Blackpool and Manchester with the Olympics torch Saturday.
