Tom Cruise wants Katie Holmes to play a villain in the next 'Mission: Impossible' movie.

The actor — who stars as spy Ethan Hunt in the action franchise — is desperate to work with his wife and believes an evil part for her in the fourth film would be perfect because he doesn't want them to play a couple on screen.

A source said: "Tom is very excited about taking 'Mission: Impossible' in a new direction and he sees Katie as a big part of that.

"They have wanted to work together for a while now but the idea of being a couple on screen in a romantic comedy is a bit dull. This might give them a chance to have some fun both as a couple and as hero and villainess."

Katie — who has a three-year-old daughter, Suri, with Tom — recently admitted she loves bringing her home life into her acting roles.

She said: "In my own life, my whole world really revolves around my family. I do what I need to do, but it's like: 'How is everybody else doing?' And it's wonderful for me as an actress to put some of that into a character."
