One of the things I've always enjoyed is moving around and staying fit. Physicality is such a big part of being an actor, but it's also about stillness and silence.

I remember my brother Nash had just directed me in 'The Square,' and I was sitting in Australia going: 'No one's called me about working for ages. I don't know if I'm ever going to get another job.

The Great Gatsby' ticked so many boxes for me.

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.

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 first video I ever watched was on a Beta system because everyone thought Beta was the way but then it ended up being video so we backed the wrong horse.

I'm hardly digging trenches for a living. I'm getting to tap into my boyhood fantasies of being a larger-than-life character.
