Raging Bull (1980): Well, of course we have to start here. Greatest boxing movie ever? That's not too much of a stretch. What more can we say that hasn't already been said? It's all so obvious. Robert De Niro famously transformed himself inside and out, packing on the muscle to play the volatile former middleweight champion Jake La Motta. In gorgeous, intimate black-and-white with its haunting title sequence, this may just go down as Martin Scorsese's brutal masterpiece. It earned Academy Awards for De Niro (best actor) and for Thelma Schoonmaker's editing, but was criminally robbed of the best-picture prize, which went to "Ordinary People."
