Raging Bull - 1980
Some people sweat that this is the best film every made because of the acting and storyline. They may have a point, its definitely in my top ten anyway. A must see if only for the opening scene in the film.
An emotionally self-destructive boxer's journey through life, as the violence and temper that leads him to the top in the ring, destroys his life outside it. When Jake LaMotta steps into a boxing ring and obliterates his opponent, he's a prizefighter. But when he treats his family and friends the same way, he's a ticking time bomb, ready to go off at any moment. Though LaMotta wants his family's love, something always seems to come between them. Perhaps it's his violent bouts of paranoia and jealousy. This kind of rage helped make him a champ, but in real life, he winds up in the ring alone.
