Washington, Apr. 18 : Former World Heavyweight Boxing Champion Mike Tyson wants one more fight, but not against his former heavyweight boxing contemporaries Evander Holyfield, or George Foreman, but against James Toback, the director of the new documentary, "Tyson," which premiered last night in Los Angeles.

When FOX News asked the former champ who he might want to knock around for a few rounds, Tyson replied: "James Toback."

"I don't know. I'm not too interested in fighting no more. I don't got the same desire ... to strike somebody in anger that I once had. It's just not the same," Tyson was quoted, as saying.

The seemingly chastened star, whose life from the mean streets of Brooklyn to the top of the sporting and entertainment worlds, and back down again, is chronicled in Toback''s film, seemed unsure of his feelings in looking back.

"I think in life there are many regrets. But you can't change the past, and I try not to allow it to chip at me and break me down. But ... there is a tremendous amount of regret," Tyson said.

Toback shed a little more light on why the former star still commands enough attention to warrant a feature-length documentary.

"He's an iconic, graphic figure, probably the most fascinating figure in sports history in the last fifty years," Toback told FOX News. (ANI)
