20. Frank Capra
Capra was one of America’s most influential directors during the 1930s, winning three Oscars as Best Director. The Italian immigrant began in comedies (1934’s It Happened One Night was the first to sweep the top Oscars), then made relevant films about humble men facing venal capitalists: Mr. Smith Goes to Washington, Mr. Deeds Goes to Town, It’s A Wonderful Life. Known for introducing the concept of spot improvisation, Capra perfectly synchronized tempo and action in his movies.
