The tricky thing becomes: Do you know yourself well enough to then portray that on screen? And for me, I find that really hard. I'd rather hide behind accents and funny walks.

The Great Gatsby' ticked so many boxes for me.

It feels good to be fit and strong.

Whereas 'Avatar' and other movies get shocks out of their three-dimensionality, 'Gatsby' is going to be about inviting the audience into this larger-than-life drama, letting them almost be inside the room rather than looking at it through the window. I think it will really work.

There's the pressure of being a No. 1 on the call sheet, being a lead actor. There's almost this feeling like being captain of the team. You want to put a bit of energy into actually setting a good example.

The sum total of all my stop-starts have made me less concerned about the future. I'm just aware now that I'll always land on my feet somehow.

When people are really great at what they do there is no aggression because they are comfortable in their own skin. They know themselves well enough that you don't have anything to prove.
