I'm thinking about what Ritt said about youthful reaction to the picture as a harbinger of what was coming down the road.
My Dad would turn 100 next week. He was a WWII vet. Hud was 34 and that would make him born 1928. Hud enlisted when he was 17 and that would be just as the war ended in '45. So they would be of the same generation. Homer looks to be in late 60s as people in their 60s often looked backed then. So Homer and my Grandpa would be contemporaries, too. Guess what I'm saying is that Lonnie would be part of the targeted generation, a [fringe] Boomer, that Ritt would have had in mind.
Paul Newman, also a WWII veteran, was born in 1925 and would have been 37-38 when HUD was filmed. Entirely too old and chock full of life experience to behave as he did, imo. I suppose Hud was supposed to be much younger than that.
