Boxing legend Rocky Marciano is coming to the big screen in his first authorized biopic, according to The Hollywood Reporter.

Morris S. Levy's M.E.G.A Films has acquired rights to Marciano's story from his family and will produce a feature from a script by first-time writer Terri Apple.

The film will follow Marciano from childhood in blue-collar Brockton, Mass., to his 1969 death in a plane crash. He was the only champion boxer to retire from his professional career undefeated, ringing up six heavyweight championships and 49 straight wins, 43 by way of knockout.

The fighter's younger brother, Lou, gave Levy and Apple never-before-revealed details about the athlete's life, including his relationship with his wife and father, for an original draft written before the writers strike.
