Raging Bull is arguably the finest work from the Scorsese and De Niro partnership. De Niro gives an amazing portrayal of a man whose animal side lurks just beneath the surface, ever ready to erupt. Vivid and unremitting in its uncompromising brutality and honesty, the fight sequences are famed for their realism. Violent throughout, this film is a testament to Scorsese's an De Niro's skills, creating a thoroughly absorbing film about such an unlikable character. Renowned for throwing himself into the roles of his character, De Niro went on a diet to gain fifty pounds during production for the role of the faded star.
