Robert De Niro and Boxing

No stranger to the squared circle, Robert De Niro won the Best Actor Academy Award for his portrayal of Jake LaMotta in the biopic Raging Bull (1980) and starred in the sports comedy Grudge Match (2013) with Sylvester Stallone as aging boxing rivals coaxed out of retirement to fight one final bout. De Niro now portrays legendary trainer Ray Arcel in the film Hands of Stone—a biopic of former welterweight boxing champion Roberto Duran—which debuted in theaters on Aug. 26, 2016.
