G-String Avatar?

Avatar star Sam Worthington says during rehearsals a stranger caught him wearing a G-string. "We were wearing nothing but lace g-strings, a couple of gears and a wig. I thought Hawaii was going to be a holiday, to be honest, I thought I'd take my surfboard and go surfing. We get there and we work and this guy comes past and says, 'What are you doing?' I said, 'We're making a movie.' He says, 'Big budget movie. Who's the director?' I said, 'That bloke over there'. And there's Jim with a handycam. He goes, 'Is that James Cameron? F**k, he's gone downhill since f**king Titanic!'"
