I believe there are two different methods of showing 3D movies, one requires the red and green spectacles and the other requires polarised spectacles. In the 1950's 3D films required two projectors and two strips of film running in perfect synch and the use of polarised specs. In the 1960's when 3D made a bit of a revival the red and green specs were used for a single film strip process witch saw two images overlayed on each other on a single strip of film and the 3D effect achieved by wearing the red and green specs, apparently it wasn't as impressive an effect as the dual projector polarised system. Stephen Speilberg is working on the patent for a system of 3D cinema that requires no glasses or accesories worn by the viewer. Be interesting to see if it works!!
