"It was only decided a couple of weeks ago, but I will be writing the script for Danny," he said. "Maximum City is a non-fiction work, so it will be a huge challenge to find the story in it. It is a wonderful book and I used it in my initial research for Slumdog. There are some great characters in the book, but no stories, so my job will be to get the fictional out of a non-fictional story."
The book is part travelogue, part memoir and gives a colourful overview of Mumbai's history and people. Beaufoy said he was discussing the need for huge creative license in adapting the book for the big screen.
"Suketu is very understanding about my creative input and flexible about many changes. I will have to come up with something to bring together all the characters from the book into something that can make a film," he said.
Beaufoy said that the real star of the film would be Mumbai itself. "It's such a vibrant, young city. Whereas in London, everything is in a sense hidden away, in Mumbai it's just all there in the open - all the emotion, all the characters," he said.
