Celador Films and Film4 have greenlit Danny Boyle’s “Slumdog Millionaire,” with Warner Independent Pictures and Pathe in advanced negotiations to take domestic and international rights, respectively.

Based on true events, script by Simon Beaufoy (“The Full Monty”) concerns an illiterate street kid from Mumbai who wins the jackpot on the Indian version of “Who Wants to Be a Millionaire?”

Brit newcomer Dev Patel, who appeared in the Channel 4 teen series “Skins,” has been cast in the lead role.

Pic will shoot in Mumbai beginning Nov. 5, fully financed by Celador and Film4. Celador’s co-managing director Christian Colson is producing, with Celador founder Paul Smith and Film4 topper Tessa Ross as exec producers.

Boyle will work with regular collaborators, including cinematographer Anthony Dod Mantle, alongside an Indian crew.

Boyle’s previous films with Film4 include “A Life Less Ordinary,” “Trainspotting” and “Shallow Grave.”

Celador was the original TV production company behind “Who Wants to Be a Millionaire?”

Smith subsequently launched the film arm, run by Colson, with the resources to co-finance its own projects. “Slumdog Millionaire” will be its fourth move, following “Dirty Pretty Things,” “The Descent” and “Separate Lies.”
