Nicole Kidman says she vowed never to make another film with Tom Cruise - even before their marriage split.

The actress previously starred alongside her ex in Days Of Thunder, after which they married, Far And Away and in Stanley Kubrick's Eyes Wide Shut.

But Kidman says she ruled out another collaboration after fearing for the sanctity of their marriage, which eventually ended in 2001.

Director Anthony Minghella offered Cruise the lead in Cold Mountain and Kidman says she would never have accepted the role of Ada Monroe in the civil war epic if he'd taken it.

She said: "We did not want to make a movie together again. There is something about on-screen coupling that doesn't work.

"I certainly wouldn't put myself through it again if I ever ended up in a relationship with an actor, because it's not worth it. There is something about protecting the sanctity of marriage."
