London, May 6 : Hugh Hefner has given Robert Downey, Jr. his stamp of approval to portray the Playboy mogul in a planned biopic.

Earlier, the `Iron Man' star had expressed his desire to play the octogenarian in his life story.

And, now, the Hollywood actor has been got the green light from Hefner himself.

"Downey and I have talked about it and it is a very real possibility," the Daily Express quoted Hefner as telling Hollyscoop. com.

He added: "He''s a marvellous actor and I would be honoured if he decided to do it." (ANI)
