Des hommes sont nés

It doesn't matter what movie you're talking about, the guy just never had an inauthentic moment on film.

He could be playing priests, professors, attorneys, soldiers, homeless guys, doesn't make a difference. He was always believable and interesting to watch. I cherish these actors because they're rare. It's interesting to me that he was with Katherine Hepburn because she's another like him. Completely authentic in everything she did.

Meryl Streep is another one. Montgomery Clift. Jimmy Stewart. Kathy Bates. Henry Fonda. They're rare. The only modern one I can think of who is pretty consistent and not retired yet is Denzel Washington. Definitely Morgan Freeman but not sure if he's retired. Michael Caine just retired.
