"The year after Avatar was just emotionally overwhelming. I was traveling all over the world, waking up in different time zones. Your body gets exhausted, and by the end of the year I just collapsed… I was in Paris training for Colombiana, sitting in my hotel room, and I couldn't stop crying. I couldn't stay awake. I must have slept for an entire month. It took me the rest of the year, even as I was working and shooting Colombiana, to pick myself up. Thank God my family was there."
