If you try to act, you're going to look like you're acting. So don't act.
Even 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.
