The Ten Faces of James Stewart

The Role: Stuffy and aristocratic Tony Kirby (James Stewart) falls for Jean Arthur, but can he stand her eccentric family?
The Movie: The Frank Capra-directed adaptation stars Stewart as the wealthy and straitlaced Kirby, who falls for the daughter of Lionel Barrymore, a wealthy, tax-dodging eccentric who gave up the world of business for personal freedom and whimsy. The movie went on to win the Best Picture Oscar.
Stewart's Contribution: Stewart shows that he can play the straight man, even as his character comes to value individualism just as much as status and success.

You Can't Take It With You, Mischa Auer, Jean Arthur, Edward Arnold, James Stewart, Ann Miller, and Mary Forbes, 1938.
