If the Pajamas Fit...

Robert Downey Jr. is a wanted man.

Brett Ratner is courting the Iron Man star to slip on Hugh Hefner’s silk pajamas in his planned Hefner biopic, the tentatively titled Playboy.

“Robert Downey Jr. agreed to do it based on the script,” Ratner told EW.com. “We’re gonna hand him the script very shortly. He loves the character and the role and we’ve been meeting with him on it. So, if he wants to do it, we’re excited to have him.”

Downey’s on a roll. He’ll follow the massive success of Iron Man with a supporting turn in the buzz-worthy Tropic Thunder in August, and he’ll appear in The Soloist in the fall.

A turn in Playboy could be high-profile and meaty enough – no pun intended (seriously).
