Speaking to Playboy magazine about his upcoming role opposite Douglas in the upcoming Steven Soderbergh-directed HBO flick, Damon said his previous aversion to dropping trou in front of the cameras went out the window in his latest role.
"Normally I'd say no to nudity, but I just did a lot of it playing the longterm partner of Liberace, Scott Thorson, in Behind the Candelabra," he said. "I mean, it's tastefully done...but the movie's not going to be for everyone.
"For one scene, I had to come out of the pool, go over to Michael Douglas, straddle him on a chaise lounge and start kissing him. It's not like I kiss him just once. We drew it up like a football plan."
And as for his costar's lip-locking skills?
"Michael was a wonderful kisser."
But don't expect that kind of kiss-and-tell from his personal life.
"The narrative about me kind of goes, 'He's a boring married guy,' which is great, because I don't get any of that other stuff like Brad Pitt and George Clooney do...People think I'm kind of vanilla and they leave me alone to work, have an actual private life and be a husband and dad."
And a movie star, albeit one who seems like he's come to terms with what may be (though hopefully not) the end of his involvement in his most famous role.
"You know what? They might have taken the Bourne series out back and shot it in the head," he said when asked about continuing in the action franchise, which detoured this year with a Jeremy Renner-starring installment. "If that's the end of it, that's just the end of it. I hope not. I love the character and the three movies we did, so I'd love to figure out a way to do another one."
That goes double for us.
