3D Films: Doomed by Evolution?

Via Roger Ebert, Walter Murch says yes:

The biggest problem with 3D, though, is the "convergence/focus" issue. A couple of the other issues -- darkness and "smallness" -- are at least theoretically solvable. But the deeper problem is that the audience must focus their eyes at the plane of the screen -- say it is 80 feet away. This is constant no matter what.
We can do this. 3D films would not work if we couldn't. But it is like tapping your head and rubbing your stomach at the same time, difficult. So the "CPU" of our perceptual brain has to work extra hard, which is why after 20 minutes or so many people get headaches. They are doing something that 600 million years of evolution never prepared them for. This is a deep problem, which no amount of technical tweaking can fix.

Read the whole thing, which has a lot of detail I left out. Bottom line - it sounds like 3D is an expensive gimmick that most people simply can't adapt to, through no fault of their own...
