The 36-year-old, who has given hits like "The Proposal" and "Green Lantern", said he always wanted to do something adventurous with his life and also tried his hands on trekking, reported Daily Star.
"When I was a kid, about 15 or 16, I did a year of a survival school in Canada called Trek. You do a year's worth of school in two months and then you spend the remaining 10 months in the wilderness in British Columbia. You live in the Rocky Mountains, on glaciers. You have to set up camps and learn to feed yourself with nothing. It was really life-changing.
