So was Mumbai fully peaceful for Danny Boyle?
"I don't know whether 'peaceful' would be the right word.For me it was a very happy experience. I got so attached to the city, they had to stop me from filming and push me out of Mumbai.
The only way to make a film based on Mumbai is to accept how extraordinarily complex and interesting the city is. If you go from the outside to make a film in Mumbai thinking you'd be fully in control of the situation and blah blah, the film would never get made.
If you trust and respect the city it delivers back to you ten-fold."
Danny has spoken to Anil Kapoor about making another film in Mumbai. "Yes, I did speak to Anil Kapoor about making another film. And if all goes well, I'll be back to do another film.
It's such an amazing city. He's a wonderful actor. But he never forgets his producers' hat. He's always surveying the situation, cutting deals.I might be coming back. I had a seriously amazing time.
One reason why the film works is the city's vivacity that we've captured on screen. It's been a while since we saw Mumbai in this light."
Danny hopes Mira Nair would be able to make her second Mumbai film Shantaram after Salaam Bombay. "If Slumdog Millionaire works for a mainstream audience international studios would be encouraged to make mainstream films.
Slumdog Millionaire has got a big heart, so I don't see why it should work for a global audience. There's a line in the film where a character says, 'India has become the centre of the world now.' People outside are now warming up to India.'
There's a risk that Danny Boyle's film would be seen to be portraying India as a slum as Roland Joffe's City Of Joy and Nira Nair's Salaam Bombay were.
"The word slum in my film's title has not been used in quite the obvious way. Working in the so-called slum areas of Mumbai I found it a fantastically organized place to go. The people were hugely generous. They are a huge community of very dignified and warmth people.
I hope my film has captured their dignity. They're not portrayed as poor and desperate people in my film.I think people in India should see the film before judge it."
That may not be as easy as it sounds, since the film has yet to get an Indian distributor and won't be released in India when it opens worldwide in November.
When contacted about Danny Boyle's next Mumbai film Anil Kapoor said, "I'll speak about this only after the London Film Festival."
