Nicolas Cage wore a voodoo 'mask' to help him get into character for 'Ghost Rider: Spirit Of Vengeance 3D'.

The eccentric actor returns as stunt biker anti-hero Johnny Blaze - who sells his soul to the demon Mephisto leading to him to become his flaming skulled alter-ego - in the film and to help him get into character he applied make-up and wore items to channel the spirit world.

In an interview with The Sun newspaper, he said: "There was a writer named Brian Bates who put forward the notion that all actors, whether they know it or not, come from a long distant past of medicine men and Shamans.

"So I would paint my face with black and white make-up so it looked like a skull - like some sort of Afro-Caribbean voodoo icon or a New Orleanian voodoo icon. And put black contact lenses in my eyes to look more like a skull - you couldn't see any white in the eyes.

"And I'd sew ancient Egyptian artefacts into my costume, get some rocks that had alleged frequencies too.

"Who knows if it works or not? The point is it stimulated my imagination to think I really was this character.

The second instalment in the 'Ghost Rider' franchise included filming in Romania and Turkey and Cage said he freaked out some locals when he turned up off-set dressed as a shaman.

He added: "If you have a Christmas party in Romania and you're shooting until 2am and you're invited to go the Christmas party and some schnapps is involved and you're still in character, all hell can break loose. And it did. I'm lucky I'm not in a Romanian prison."

'Ghost Rider: Spirit Of Vengeance 3D' is in cinemas later this month.
