Yeah, GWTW was shot in full-frame, as was Casablanca, The Wizard of OZ, etc. If it was shot in academy ratio, that's how it should be seen.
Please don't think me arrogant, but just out of curisity, did widescreen exist prior to the 1950s? Wasn't the first picture filmed in cinemascope The Robe? Understand, I mean no offense! I'm just wondering.
