Jimmy Stewart acting was ahead of its time
They say Brando was the one who revolutionized acting. No question Brando contributions to film acting. But I believe Stewart may have started this naturalistic style acting earlier.
Watching this film and It's a Wonderful Life made me convinced how great an actor he is, just those two films alone. And I believe he's better than most well known actors today.
The guy can do it all, from playing subtle, nuanced to intense, volcanic to silly, funny. The guy was/is a genius actor.
One of all the time greats.
