If you were on the fence about buying a ticket to see Marty Supreme in theaters, we have a brand new reason it will be worth the price of admission: Timothe Chalamets derrire.While some actors choose to use prosthetics or body doubles to film nude or intimate scenes, Chalamet decided to decline using a butt double during a scene where he was being spanked. Before you start thinking Marty Supreme is a kinky film, the scene involves entrepreneur Milton Rockwell (played by Shark Tanks Kevin OLeary) offering table tennis champ Marty Mauser (Chalamet) the opportunity to play in the upcoming World Championships if he agrees to be spanked with a paddle in front of a room full of people. But in a new interview with Variety, OLeary revealed that Chalamet refused to use a body double for the pivotal scene. When it came time to whack him, there was a stunt ass. There was a double, OLeary said. [Chalamet] wouldnt do it. He said hell do it himself. He didnt want some other ass immortalized. Despite it being Chalamets real backside, the shoot wasnt easy. To soften the blow, OLeary was supposed to use a fake paddle, but the prop broke on the first whack, and he had to swap it out for a real one. Then, the scene went on for hours because director Josh Safdie demanded they do 40 takes that lasted until 4 a.m. Josh was saying, Youve got to wind up harder,' OLeary recalled. I was really whacking him.
