How did you do that scene underwater while you were tied to the chair?
I learned how to scuba dive, so I was underwater for about half an hour at a time, a couple of times. I had scuba guys near me that would bring the air in to me, as soon as I started feeling like I was running out of air. I would just shake my shoulders and in they would fly, and I would sit down there for about half an hour. I lost all of my senses except for hearing because they had a loud speaker underwater so that the A.D. could say, "They're pulling focus right now. The camera's moving to you. Jesse's swimming in," so that I knew what was happening. The very first time I went down, I couldn't hear anything. I had no senses and I felt completely lost and I panicked and swam back up to the top. We decided this was the way I was going to feel safest underwater. It ended up working out.
