Filed under: Cinematical, Best and WorstDirector Sidney Lumet, who passed away April 9 at the age of 86, may not have been a "name" director, like Steven Spielberg or Alfred Hitchcock (at least not to the general public), but you certainly know the names of his films. From 1957's '12 Angry Men,' to 'Dog Day Afternoon,' 'Serpico' and 'Network,' in the '70s and 'The Verdict,' in 1982, Lumet's movies were searing documents that questioned the social issues of their day.
