First we pre-visualized it [the flying fish scene in 'Life of Pi'] so the actors could act. It took a long time to get that to come to life and to design those coming out of the screen. We had great fun with that. It takes a long time, a year maybe.
Ang LeeEven dramatically how you position some person, the depth, the existence [in 3D] is different than a flat image even though by itself it has depth, we create the illusion of depth. For example, some of the shots I have to stay closer to the actor because it's a young actor, I like it closer for some of the shots. I watch 2D scenes next to the camera, then when I go back to my station and watch it in 3D I have to go back and reduce his acting, he has to shrink a little bit because he peeks out more.
