‘I was spanking myself’: Matt Damon jokes about bruising his butt cheek during ‘rough’ Suburbicon sex scene with Julianne Moore

He’s no stranger to physically rough movie scenes, having starred in four Jason Bourne films.

But Matt Damon, 47, joked during an interview with Julianne Moore, 56, on ET that things were tougher on the set of George Clooney’s new film, where he took a ping pong paddle to his own butt during a sex scene.

‘[On] Jason Bourne I’m fine. But I roughed myself up on Suburbicon,’ he explained.
