What an incredible cast - Brando, Pacino, Caan, Keaton, Deniro, Duvall, Talia Shire, Richard Castellano, Abe Vigoda, Lee Strasberg, and a terrific supporting cast. No wonder this is regarded by many as the best movie series of all time (minus Gf 3)The scene late in Godfather 2 when Michael walks in on Kay secretly visiting the kids and closes the door on her is a masterclass of wordless acting.
Keaton's face going from terrified to resigned to anguish was extraordinary.
