19. Manhattan (1979)
Arguably one of Woody Allen's greatest films shows New York as you have never seen it before. Brilliant Gordon Willis cinematography simply adds to the terrific story of friends finding and losing love in the Big Apple.
20. Night of the Living Dead (1968)
George Romero's zombie classic set the standard for hundreds of horror films to come. Unlucky folks are trapped in a Pennsylvania farm house, trying to fight off flesh-eating zombies and eventually each other. Incredible tension with an authentic feel. A nightmare come to life.
21. The Best Years of Our Lives (1946)
William Wyler's heartbreaking and moving ode to WWII veterans returning home from combat. A near perfect film, with a nostalgic portrayal of suburban America leading in to the 1950s. Hugo Friedhofer's musical score is one of the greatest in film history.
22. Young Frankenstein (1974)
Mel Brooks hit the jackpot with this puppy, one of the great box office hits of all time. But Brooks respected his subject matter, making a near-perfect parody of old-time Universal horror films - including Bride of Frankenstein - which could only be created in glorious black and white.
23. The Defiant Ones (1958)
Stanley Kramer's insightful story of two escaped convicts (Sidney Poitier, Tony Curtis) chained together while on the run in the Deep South. Symbolic tale is highlighted by fantastic supporting performances and an unforgettable ending.
24. The Bicycle Thief (1949)
Italian director Vittorio De Sica's moving masterpiece tells the seemingly simply story of a man who loses his bike, and the difficult week he spends with his son. One of the most beautiful films ever made.
25. Portrait of Jennie (1948)
Director William Dieterle's haunting tale of lost love told from the viewpoint of tortured artist Joseph Cotten. He meets a ghost in Central Park (in the form of the lovely Jennifer Jones) and eventually paints her mysterious portrait, the final shot in Technicolor. One of the most underrated films of all time.
My apologies to Citizen Kane, Casablanca and The Seven Samurai, films which frankly would have been better in color.
