Robert Downey Jr. is most probably the next ultimate Playboy. The real life Playboy Hugh Hefner has reportedly chosen the "Iron Man" star to play him in his biopic.

Sources say that the 82-year-old magnate took a liking to the actor after watching his current superhero flick. He allegedly admired his humor and acting skill in the film.

The film is expected to shoot the earlier scenes in Chicago where Hefner grew up. No word yet on when the movie will begin shooting.

According to the Chicago Sun Times, a rep for Downey Jr. said he's interested with the project but will not commit until a script is done and a director is named.
