Former Middleweight Champion and colorful and controversial pugilist Jake LaMotta, best known to film going audiences for the gritty, hard-nosed bio pic that showcased his life, Raging Bull, is now the subject of a full-length feature documentary.

LaMotta, 92, is collaborating with Greg Olliver, best known for co-directing and producing Lemmy, the much-lauded film about the Motorhead frontman Ace of Spades, Lemmy Kilmister. Oliver also has projects such as a documentary about a WWII Commando and blues stalwart Johnny Winter in the works.

The LaMotta project, which already started filming in Arizona back in January of this year, will feature interviews with fellow athletes such as Mike Tyson, as well as actors, family, and friends, all whom are sure to give a keen insight to the complex and emotional boxer.
