London, Dec 18 - Hollywood actor Sam Worthington has revealed he enjoyed stripping off for his role in 'Avatar' because he loves to be naked.

The Australian actor who stars as a blue alien called Jake Sully in the 3-D animated film by James Cameron insists he didn't solely rely on technology for the role, reports list.co.uk.

'I had nothing on. I had a loincloth on and they painted me blue, basically,' he said.

'I was thinking if this is how you make a big budget movie, then I'm mad enough to be a part of it. I would do that most times, doesn't matter if James Cameron wants me to do it. I do it most times. He had to struggle to put clothes on me,' he added.

The 33-year-old also credited Cameron for changing his life and career.

'Before I met Jim I was sleeping in my car. He's plucked me from obscurity. He changed my life, so to speak,' he said.
