I stand corrected. I think I saw half of GWTW about thirty years ago.
1962 as a part of my reading program I read GWTW while a lifeguard. I went to Squadron Officers School as a 1st Lt and spent 3 months in Montgomery Alabama. It was 1968 and there was a theater in town where the movie had been continuously shown since its opening in 1939, (this was 1968.) I wonder if it's still being shown there?
