Jake Gyllenhaal Late Night With Jimmy Fallon on 26th May 2010.
"You know, the first 35-foot, 40-foot jump on a wire without much practice is scary," Jake said.
"It does just get fun and it gets, unfortunately, dangerously more and more fun, and then you want to do it without a wire and then you jump farther, and then everybody's flipping out and then you're getting phone calls from Jerry Bruckheimer, like, 'Please, this is why we have stunt men," Jake said.
To play the role, Jake needed to be in peek physical condition.
When Eyewitness News entertainment reporter George Pennacchio tried to throw him a curve ball, he caught it and threw it back with more comedy.
"The people who gave you these prosthetic muscles on your arms did a fantastic job," said George.
"We had an incredible crew of prosthetic people every day. I was in the chair from, you know, 3:30 in the morning until at least 6 in the morning. It was a three and a half hour process. You'll see the extras in the DVD", Jake joked". Source: abclocal.go.com
