Los Angeles - Michael Douglas says Matt Damon is a tender kisser.
The pair filmed gay sex scenes for Behind The Candelabra and the 68-year-old actor admitted he enjoyed locking lips - even if the Promised Land star joked he imagined Michael's wife Catherine Zeta-Jones.
The Wall Street star told the Mail on Sunday newspaper's Event magazine: "Matt says when he kissed me, he thought of Catherine. She was very pleased by that ... I thought of Matt.
"There was a tenderness about him. The way he kissed."
'Obsessed with body waxing'
Michael commended his co-star, calling him "brave" for taking on the risqué role at the "prime" of his success.
He explained: "When Steven [Soderbergh, the film's director] told me Matt wanted to play Scott I thought, 'Wow, that's brave'. It's my time to do what I want, but he is Mr. Bourne Identity, in the prime of his leading-man career.
"Matt's in a group of really impressive - Brad [Pitt], George [Clooney], Matt and Ben [Affleck] - willing to take chances. It surprised me - in a good way."
He also revealed Matt became "too obsessed" with body waxing for the role.
He joked: "Matt got a bit too obsessed - thee was one point I was getting worried about him."
