Was TPM trailer officially released in half or full sbs? If that's true, might make sense to take your 3d creation system, attempt a shot or two shots and see how they comparison to everyone.
The presentation at the recent Celebration for the AotC 3D had some great photos of the length they were going to get the depths they felt worked. But they had the 3D geometry to play with. Two clips they focused on were Obi talking to Dexter and part of the Zam chase. With the Dexter clip they could ratchet the 3D effect to pull his nose toward camera or foreshorten the character in relation to the background.
