The days of exploration of Shackleton and Scott are long gone. Everything has been climbed, crossed, done. Now what we're exploring are the full boundaries of human endeavour. It's not physical - it's all in the head.
I would love to do a western. I would love to play an explorer. That is always something that has really captured my imagination since I was a kid, like James Cook or Magellan or Earnest Shackleton.
