The 48-year-old actor used to enjoy changing his hairstyle but insists he now plans to stay the way he is and won't be growing out his locks in the near future.

Discussing his role as Cameron Poe in 'Con Air', he told Empire magazine: "The look was a little bit country, more of a Southern look from the 70s.

"I've always tried to experiment with different looks, but I've stopped doing that now.

"You probably won't see me doing any different hairstyles for a long time."

Nicolas also admitted he "flipped out" while filming 'Face/Off' though he isn't sure why the movie - which saw his character swap faces and personalities with John Travolta's alter ego – disturbed him so much.

He added: "That was a dark experience. There's a scene where I'm in prison shouting, 'I'm Caster Troy' and if you look carefully at that scene, there's a moment where I look really scared.

"I don't know what happened, but it really flipped me out. I got really scared I was locked into that situation

"The idea is to make it looks easy and to have fun with it, but the subject-matter, even though it was far out, got in my head at times and it wasn't always pleasant."
