The general has retired, but since I've just stumbled on this post I took some time to check the YouTube link an watch the trailer for "Island in the Sky".
Well you can't really judge a movie on a trailer alone, but if the footage between 01:50 and 02:23 is indicative, I'm glad for John Wayne's memory that we haven't remembered / seen this performance!
It is a shame that the TV companies don't air more classics, although DVD does redress the balance (somewhat).
Ah, still don't have a PAL DVD (R2) version of "The Hill" nor the original wide screen version of "Hell in the Pacific".
