Playboy boss Hugh Hefner will veto any film about his amazing life unless "Iron Man" Robert Downey, Jr. plays the lead.
 
The tycoon is convinced Downey Jr. is the only actor who can play him on the big screen, and the publisher told the star just that when they met on the red carpet at the "Iron Man 2" premiere in Los Angeles on Monday night.
 
Hefner says, "I told him, 'I couldn't do better'."
 
The Playboy boss admits he's still waiting for the right screenplay, but the "Sherlock Holmes" star will get the call when the film is ready to go.
