I maintain you can’t do a good conversion of a two-hour movie with high quality in a few weeks like they tried to do with Clash of the Titans.
You see another stumble with the most recent Harry Potter movie from the same studio making the same mistake – except really getting spanked for it now because they didn’t get the film done.
They announced it in 3D – threw a bunch of money trying to convert it to 3D in post-production and it simply didn’t work. They just didn’t get it done.
It’s pretty simple and I agree with James Cameron that if you want good quality 3D you should shoot in 3D. I enjoyed watching Avatar in 3D, in the theater. Glasses-free 3D? Cameron says within a decade:
Once we get to auto-stereoscopic, that’s watching 3-D without glasses, it is going to be the way we watch all of our media. That’s probably eight to 10 years away.
