Some great and informative replies here to my first question. And special thanks to the programmer who offered the reasons why it's difficult. But was still hoping to hear some possible explanation as to why even when 3-D is used on tv and some movies, the red/green technique is used instead of the better Polaroid glasses. Is that also a matter of expense? For that matter with the clarity of DVD why haven't some of the old 3-D films been released on DVD in the polarized process. Would really love to know if there are technical reasons for that. Thanks to all the informative and interesting responses.

Being new to the board I tried a search of 3-D before posting this query and suggestion. In the seventies a local NY station broadcast Gorilla At Large, Creature from the Black Lagoon, and Revenge of the Creature in 3-D using the red and green process converted from the polaroid. It would seem that TCM would be the ideal place for a festival of 3rd Dimension films from the 50's and even perhaps a great special documentary on the 3-D craze of that period. As a kid growing up in a small town I only got to see the movies in their 2D release. Have seen a few in festivals, but would love to see the ones I missed. Does anyone know why for some technical reason this hasn't happend? Medium recently used the red/green process to some good effect but why not try the polaroid process for brighter pictures and greater depth? Would be interested in knowing more about why more 3-D hasn't been done on tv, and if TCM follows the boards would like to suggest they think about a retrospective of the 3-D films in their library.
