Matt Damon Excited to Make Out With Michael Douglas in Liberace Biopic

Matt Damon is getting ready to star in the upcoming Steven Soderbergh-directed and Jerry Weintraub-produced “Liberace” – a biopic on the life of famed entertainer and pianist, Wladziu Valentino Liberace.

But in particular, Damon is preparing to lock lips with co-star Michael Douglas – multiple times.

“It is scripted that there’s more than one (kiss),” Damon told FOX411’s Pop Tarts at the premiere of Jerry Weintraub’s autobiographical HBO documentary "His Way" in Los Angeles last week, adding that he hopes the film’s costumes will be “really, really crazy.”

Douglas will play Liberace while Damon takes on the role of his significantly younger longtime lover, Scott Thorsen.

“I’m really excited about the movie and Michael is excited too. They’re two really great roles and we’re really looking forward to it,” Damon said. “I never thought in my life I would get to kiss Michael Douglas.”

Damon starred alongside Douglas’s real-life wife, Catherine Zeta-Jones, in “Ocean’s Twelve,” but they never got to share a kiss – so for Damon, it seems this is the next best thing.

“I’m a little upset that I didn’t get to kiss Catherine but now I get to kiss Michael! I thought it would have been better if I could at least kiss them both. I think of it in algebra terms, back to my high school days, it’s the transitive property,” he said. “I am making out with Catherine (by first making out with Michael).”

The blogosphere has been abuzz over recent weeks that “Liberace” will be Soderbergh’s last Hollywood hurrah.

“I’ve had a lot of conversations with him and he is serious about retirement. After that, he says it is the last one he is going to do,” Damon added.

So could it be that the Academy-Award winning Soderbergh, who has directed/written/produced well over 30 films in his 20 plus year career, finally run out of mountains to climb?

"I have a few more issues to explore on the checklist for the next five years and then I might be done," Soderbergh told this column back in 2009. "I can feel myself running out of ideas."
