Memorable Fathers and Sons

Forgive me, Bat. I hope you don't mind that you've inspired me to create this thread, co-opting your idea. There are just so many I want to name:

EAST OF EDEN - James Dean and Raymond Massey
THE GODFATHER - Al Pacino and Marlon Brando
HUD - Paul Newman and Melvyn Douglas
CAT ON A HOT TIN ROOF - Paul Newman and Burl Ives
HOW GREEN WAS MY VALLEY - Roddy McDowall and Donald Crisp
GOLDEN BOY - William Holden and Lee J. Cobb
THE CHAMP - Jackie Cooper and Wallace Beery
ANDY HARDY series - Mickey Rooney and Lewis Stone

I'll stop there for now.
