Should Robert Downey Jr. start trying on silk pajamas? Yes indeed, Brett Ratner tells EW.com. The director (X-Men: The Last Stand) says that he’s met with and wants the Iron Man star to portray Playboy founder Hugh Hefner in Ratner’s planned biopic, tentatively titled Playboy. “Robert Downey Jr. agreed to do it based on the script,” the director says. “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.” Ratner adds, “We wanted him before Iron Man so we were ahead of the curve.” Downey’s rep declined to comment.
