That's what I get for copying and pasting from IMDb:
Shot on a 35mm Tecnirama double-frame negative (the frame is as big as two regular Academy frames joined together) running horizontally through the stop motion camera, with each frame photographed three times (once with a red filter, once with a blue filter, and once with a green filter). This negative was then printed to both CinemaScope-compatible anamorphic film and Super Technirama 70mm film.
