Slumdog Millionaire is a 2008 British romantic drama film directed by Danny Boyle, written by Simon Beaufoy, and co-directed in India by Loveleen Tandan. It is an adaptation of the novel Q & A (2005) by Indian author and diplomat Vikas Swarup. Set and filmed in India, the film tells the storey of Jamal Malik, a young man from the Dharavi slums of Mumbai who appears on the Indian version of Who Wants to Be a Millionaire? (Kaun Banega Crorepati in the Hindi version) and exceeds people's expectations, thereby arousing the suspicions of the game show host and of law enforcement officials.

After its world premiere at Telluride Film Festival and later screenings at the Toronto International Film Festival and the London Film Festival, Slumdog Millionaire had a nationwide grand release in the United Kingdom on 9 January 2009 and in the United States on 12 November 2008. It premiered in Mumbai on 22 January 2009.

Slumdog Millionaire was nominated for 10 Academy Awards in 2009 and won eight, the most for any film of 2008, including Best Picture, Best Director, and Best Adapted Screenplay. It also won seven BAFTA Awards (including Best Film), five Critics' Choice Awards, and four Golden Globes. The film was dubbed in Hindi for Indian release as Slumdog Crorepati and also in Tamil as Naanum Kodieswaran.
