Query: Black and White Masterpiece

Meticulous attention to detail and proper use of black and white photography gives this story of the self-destructive life of pro-boxer Jake LaMotta extra-added emphasis.Footnote: When interviewed, the real Jake LaMotta said the movies's depiction of his life was inaccurate - the movie wasn't violent enough!!!!He did not elaborate, and no one wanted him too.Can you blame them?
