Rushdie has a rather long Guardian piece about film adaptations in general, with a few shots at Slumdog embedded in it. Here's a good bit:
Boyle, when asked why he had chosen a project so different from his usual material, answered that he had never been to India and knew nothing about it, so he thought this project was a great opportunity. Listening to him, I imagined an Indian film director making a movie about New York low-life and saying that he had done so because he knew nothing about New York and had indeed never been there. He would have been torn limb from limb by critical opinion. But for a first world director to say that about the third world is considered praiseworthy, an indication of his artistic daring. The double standards of post-colonial attitudes have not yet wholly faded away.Some of the "poverty porn" critiques of Slumdog that floated around on the web were a bit too PC, certainly, and my own main problem with the movie had everything to do with the storytelling and nothing to do with a white guy telling it. But there is something breathtaking about Boyle's attitude here and I think Rushdie puts his finger on it.
P.S. ... I would totally go see a film adaptation of Midnight's Children that Rushdie says he's starting work on. Hopefully this time it will actually happen.
P.P.S. ... I wonder what Rushdie will think about the Watchmen adaptation? He is a comics fan with an interest in film adaptations, somebody remember to ask him this in another few weeks...
