Film The Life Of David Gale

How challenging was shooting the scene in the kitchen where you're handcuffed, naked, with a plastic bag over your head?
That scene was not easy for anybody. Everyone was uncomfortable doing that. You have to make sure, as an actor, that you really believe a scene like that makes an impact in the movie that cannot be made any other way. And you have to trust that, or else you'll deeply regret it. Personally.
It looked tough...
That was one of the roughest scenes I've ever done. It's not one of the roughest scenes I've ever acted, but it's just that the circumstances were difficult. I couldn't breathe, quite frankly. It wasn't rigged. There was a bag with tape around it over my head, and it was very scary.
