Danny Boyle’s tribute comes in line with the recent terror attacks in India’s financial capital that has shaken the whole world.
"It's a city with a big heart that's been wounded this week, but it will recover," ‘BBC’ quoted Boyle as saying.
He added: "It is weird to win this at the end of what's been a terrible week," added the Slumdog Millionaire director, referring to the attacks that killed 172 there.
"But the human spirit is dominant. They will overcome, you can bet on it."
Slumdog Millionaire, set for a January release in the UK, also won best director and best newcomer for its 18-year-old star Dev Patel.
Legendary actor, Sir Ben Kingsley, who famously played Indian spiritual leader Gandhi on film, also offered his condolences to Mumbai and its citizens.
"India will survive and move forward. They are a very resilient nation. I really hope India can shake this off, because so many people want to be there and invest there and enjoy their industry and economy," he said.
