As widely reported in the media Mike Tyson shot a promotional video for a new Indian movie.
A video report which includes some glimpses of the shot footage (showing Tyson doing boxing moves in the ring) and an interview with the director can be seen here.

"It was a pleasure shooting with Mike," the movie producer Firoz Nadiadwala was quoted. "He was courteous and friendly on the sets and spoke to everyone from the assistants to the production guys with ease."

The Bollywood film is called Fool N Final and is directed by choreographer Ahmed Khan.
It has an all-star cast and is based on the British film Snatch written & directed by Guy Ritchie. Most of the film has been shot in Brazil and Dubai. The confirmed release date is June 1, 2007.

The former boxing champion had been expected to travel to India to film for the movie "Fool n Final," but the scene was instead shot in Las Vegas because of a lack of a proper venue in India, director Ahmed Khan said.

"We could not find a suitable stadium in India to shoot with him," Khan told the Mumbai Mirror. "I was also worried about Mike's security so we decided to shoot in Las Vegas."

Khan and the producers said it was a better location and tighter security in Las Vegas that made the filmmakers opt to shoot the sequence there.

The video was shot over a two-day period.

The comedy, set for a June release, features well-known Indian actors Sunny Deol, Shahid Kapur, Vivek Oberoi, Paresh Rawal, Johnny Lever, Ayesha Takia and Sameera Reddy. In the slapstick film, two diamond-thirsty gangs clash over the loot while it is being shipped from the Middle East to India.
