The Great Gatsby' ticked so many boxes for me.

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.

To act with a tennis ball and imagine it's a tentacle, or if you're in some kind of wilderness film and you go, 'Okay, we can't have a grizzly bear here, but imagine when you step over the rock there there's a grizzly bear.' I don't know. They're tough moments.

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.

I'm single, footloose and fancy free, I have no responsibilities, no anchors. Work, friendship and self-improvement, that's me.

Basically you want as many people as possible to see your movie.

Whenever you deal with science fiction you are setting up a world of rules. I think you work hard to establish the rules. And you also have to work even harder to maintain those rules, and within that find excitement and unpredictability and all that stuff.
