Undisputed is a 2002 American sports drama film written, produced and directed by Walter Hill.

The film stars Wesley Snipes, Ving Rhames, Peter Falk, Michael Rooker, Jon Seda, Wes Studi, Fisher Stevens, and Master P. Undisputed was released in the United States on August 23, 2002.

The film performed poorly at the box-office and received mixed reviews from critics; nevertheless it later found success in the home video market.

Heavyweight boxing champion George 'The Iceman' Chambers is convicted of rape and sentenced to six to eight years at Sweetwater, a new prison in the Mojave desert.

Unaware of the prison's ways and its unique hierarchy, the pompous and bratty Chambers tries to impress upon the inmates his status as a champion boxer.

Criminals fight in boxing matches with very lax rules, thus making it a very addictive and lucrative venture for the syndicate.

The most popular boxer behind bars is Sweetwater's soft-spoken, humble undefeated Monroe "Undisputed" Hutchen, who ends up in solitary confinement after Chambers picks a fight with him in the mess hall.

Flashbacks to Hutchen's own boxing career shows that he had been sentenced to life without the possibility of parole for beating to death a man who was sleeping with his girlfriend.

Ripstein, a lifelong boxing fan, proposes a match and Warden Lipscomb is persuaded to look the other way.

Chambers knocks down Hutchen twice (and with the London Prize Ring Rules, each knockdown counts as the end of a round, as the boxer is given only 60 seconds to get up).

In the third round, Hutchen charges back and knocks Chambers down for the first time in his career, sending the crowd of prisoners into a frenzy.

The whole cell block watches the televised fight, and laugh and cheer Monroe's name after hearing Chambers being crowned the "undisputed" heavyweight champion of the world.

"[3] Hill and Giler were having lunch one day and discussed Mike Tyson, who was sentenced to prison for rape in 1992.

[4] However Hill says while the Tyson case was the departure point, "There are a number of prize fighters who have been in trouble with the law.

[7] Rhames was in peak physical condition having been preparing for two years to star in a film about Sonny Liston, Night Train, that ultimately was never made.

"[4] Hill said that "heavyweight boxing within the past 50 years has been the purview of black men with a couple of tiny exceptions.

However, according to Jeanne Corcoran, the Nevada Film Office's production manager, the prison "didn't have the right look.

"[8] Instead it was decided to shoot the film in an unopened wing of the medium-security High Desert State Prison in Indian Springs, Nevada.

The site's consensus is: "While not the deepest boxing movie out there, Undisputed is successful at hitting its aspiration of being nothing more than a genre picture.

Heck, we did it in 39 days, it cost $20 million, which is very cheap for Hollywood standards, and tells a good story.

I guess it's the literary equivalent of a short story... With all the action in it and the tough guy aspects, it's going to appeal mainly to a young male audience.

The film received three direct-to-video sequels, with a focus more centered on Mixed Martial Arts rather than boxing.
