3. High Noon
Fred Zinnemann’s High Noon is arguably the most celebrated Western film ever made. It stars the iconic Gary Cooper as an aged lawman forced to face an entire group of bandits alone. The film not only broke away from many Western film traditions with its focus on dialogue instead of action and real-time filming, but it also served as an allegory against blacklisting and defended the courage of those who spoke up against the practice in Hollywood. It lost both Best Picture and Best Director to Cecil B. DeMille’s Greatest Show on Earth.
