Speaking to Playboy magazine, Damon said: "I remember asking Heath Ledger after Brokeback Mountain, 'How'd you do that scene with Jake? - meaning the scene where they start ferociously kissing."
"He said, 'Well, mate, I drank a half case of beer in my trailer.'"
"I started laughing and he goes, 'No, I'm serious. I needed to just go for it. If you can't do that, you're not making the movie .'"
We wonder if Heath's wise words was able to help Damon prepare for is new role?
