On almost every list of the greatest American films of all time, at the top of the list, is a film from 1941 called Citizen Kane. Orson Welles' American classic continues to dazzle and impress more than 70 years later. Well, back in 1941 they felt differently. How Green Was My Valley ate Kane's lunch and forced Welles to try to be satisfied with an Oscar for Best Original Screenplay. What a chump.
