Coming from Australia and playing rugby, you just think that soccer is a bit soft, but I'll tell you what, it's not. It's rough as guts.

You're dealing immense, acute amounts of fear, which makes the rest of life a little bit easier. You don't sweat the small stuff so much.

Free-diving is all about dealing with anxiety. I've blacked out a few times. I've had big black-outs.

My strength is my distance. I can swim two-and-a-half soccer fields on one breath.

Free-diving is all about being lean, being super-flexible, and having a good breath hold.

I don't think acting should be all-encompassing. So, when I'm not shooting, I'll go down to Mexico on a spear-fishing trip for a couple of weeks, or I'll go to the Coral Sea, or I'll go to Panama, or wherever.

I think actors should stay grounded and humble and open.
