Matt Damon Makes Out With Michael Douglas & Catherine Zeta-Jones

Not only does Matt Damon get to make out with legendary actor Michael Douglas, but through Damon's reasoning, by kissing his Liberace biopic costar, he's also kissing Douglas's wife, Catherine Zeta-Jones.

"I kind of think of it in algebra terms, back to my high-school days," Damon said, according to People. "It's like the transitive property -- by kissing Michael Douglas, I am making out with Catherine."

In the film, Douglas plays flamboyant pianist Liberace, and Damon plays his boyfriend Scott Thorson.
