Harrison Ford underwent a dramatic makeover to play baseball mogul Branch Rickey in a new movie because he wanted to shed his Hollywood persona onscreen for the first time.

The Indiana Jones star shaved his head and wore a wig and a fat suit to play the sports executive in new film 42, and Ford admits he relished the challenge.

He tells the New York Daily News, "42 was the first time I could choose not to bring Harrison Ford to a film. I thought it (would work better) if people were spared the history they had with me through the last 40 years. So I shaved my hairline and wore a wig and a padded suit to resemble Rickey."

The movie chronicles Rickey's friendship with baseball's first African-American Major League player Jackie Robinson.
