Michael Douglas & Catherine Zeta-Jones

Michael Douglas has revealed he's love to work alongside wife Catherine Zeta-Jones again - but only if he can kill either her or her on-screen lover.

He said recently: "I'd be the villain, because nobody likes older guys with younger women."

"So we'll get her a young leading man and I'll be the bad guy. And I'll 'off' one of them."

But he won't do a rom-com with her: "As far as doing a romance in a film for a married couple, audiences seem to lack the excitement, knowing in the back of their mind these people are together all the time."

The two previously starred together in Traffic in 2000.
