"The Pawnbroker" with a brilliant performance by Rod Steiger, a professor who is a victim of Nazi Germany.
What "Scheindler's List" showed happening to millions of Jews, "The Pawnbroker" showed how a single Jew lost everything he ever loved and became a miserable human being in the aftermath of WW2, while living as a survivor in New York's Harlem.
The film has scenes of flashbacks to the concentration camp where he is a witness to his friends being killed and his wife forced to work as a whore for the Nazis.
It also is the first movie to be allowed the use of nudity and still be shown in theatres of the 1960's.
Probably the most depressing movie ever, yet the most social redeeming.
An important movie that never really received the credit it deserved which is why most real actors don't see the Academy Awards as a real test of a films quality but mostly a political or marketing tool.
