To be accurate, it was impossible to use an anamorphic lens with a three strip Technicolor camera and Fox had no choice. They also felt that the dye transfer prints did a lot to minimise grain which was a problem on the new larger screens.
Couldn't agree more. While it will be fun to see the 4:3 version of the Robe, I can't but think that I would rather they add in "Demetrius" instead!. It should look good as its transfers to date have always looked much better than Robe.
