Actor Val Kilmer is turning to Hollywood pal Arnold Schwarzenegger for advice about politics - he wants to become a U.S. state governor.

The one-time Batman, 48, is serious about running for office in New Mexico - where he owns a huge ranch - and is hoping to get some tips about the stresses of the job from movie action man-turned-Governor of California Schwarzenegger.

He says, "I plan to sit down with Arnold Schwarzenegger. I'm approaching this as a serious endeavour. But being famous as an actor is one thing - they take no prisoners in politics."
