Excerpt from an interview with Ang Lee from March, 10th 2009. I find the first question a bit, uhm, insensitive or something, but here goes:
Do you remember where you were when you got the news that Heath died?I was landing at the Tokyo airport when I got an email from James. Heath died during my flight. That’s always strange to think about.
What is your favorite memory of him?It also happens to be one of my favorite shots of my career: his “barfing” scene in Brokeback, when he was hitting the wall with his fists. We were on the third take, his fists were bleeding, he’d literally spilled all his guts, and something in the background struck me as being perfect. I think it was the clouds. I wanted to do another take, but Heath was totally exhausted. My producer said, “That’s bullshit. The actor has had enough.” But the clouds were perfect! We did another take, and after it was over, Heath said, “Wow. That felt good.”
