I am told that people used to look at Jimmy Stewart strangely when he turned up with his real wife at social events - people were so used to seeing him and June Allyson together as man and wife (in several films) that they sort of assumed that they were in real life !! (a bit like Terry Scott and June Whitfield in the UK!)
Agree that Strategic Air Command has some of the best air to air sequences of any film. I particularly like the high altitude shots as they transit out to Alaska in the B36 - pretty amazing..............
