Sam Worthington

When I was young, my parents were these titanic, infallible figures. But Mum's illness and Dad's battles with diabetes and heart attacks had a ripple effect on me - reminding me of my own mortality and that these illnesses are genetic.

In the movies, they make you look good and tough, but in real life, it's completely the opposite. I do these ueber roles, I think, because in real life I'm quite shy and reserved. In real life, I'm a dork.

I'm a 'Clash of the Titans'/'Star Wars' baby. I'm not a new 'Star Wars' baby. I'm not an 'Avatar' baby. That full CG doesn't work for me. I need interactivity. I need to feel the goo. I need to feel people coming out of animatronics and just interacting with props.
