I knew this would crop up eventually. I have seen poster artwork somewhere that states CinemaScope, but looking at the transfer itself it shows every indication of being a flat film and not pan and scan.
Paul, "Lost Safari", "Greatest Adventure" and "Magnificent" were 'British' productions so they were probably framed at 1.66 or 1.75. "Fight For Life" was shot in the US at MGM and is probably 1.85. I believe "Trappers" was intended for TV and is probably 1.33. Not sure about "Hidden Jungle".
Charles, Paramount released the last two Scott Tarzan's. "Tarzan's Greatest Adventure" (1959) and "Tarzan The Magnificent" (1960). The rest WB owns. "Tarzan And The Trappers", "Tarzan And The Lost Safari", "Tarzan's Hidden Jungle" and "Tarzan's Fight For Life".
