Australian star Sam Worthington, who was last seen in Terminator Salvation, says he was a bricklayer and never ever dreamt of becoming an actor.

"Nobody dreamt of acting or movies where I come from. Where I grew up, you barely had a movie house or a video store, let alone thinking you would ever have your head on a poster, so I didn't even go there. My dream was to get out of the town," Worthington said in a statement.

The 33-year-old said that acting came to him "by chance".

"I was a bricklayer. I built houses and the acting came about because of a girl. I was 19 and met a girl who wanted to go to the premiere drama school in Australia, NIDA, where Mel Gibson, Cate Blanchett and many others went," he recalled.

"She had an audition and I auditioned with her for moral support, to cheer her on. I just made my way through it in my own way and they said 'keep going, keep going', so the audition kept going and then eventually they said, 'would you like to come and spend three years here?' I got in, she didn't and that was it. She dumped me a week later," he added.

Worthington's future projects include James Cameron's magnum-opus 3-D sci-fi epic Avatar followed by Clash of the Titans, The Debt and Tell Me.
