John Joseph Nicholson is a retired American actor and filmmaker. Nicholson is widely regarded as one of the greatest actors of the 20th century. Throughout his five-decade career he received numerous accolades, including three Academy Awards, three BAFTA Film Awards, six Golden Globe Awards, and a Grammy Award. He also received the American Film Institute's Life Achievement Award in 1994 and the Kennedy Center Honor in 2001. In many of his films, he played rebels against the social structure.

The Academy Award for Best Supporting Actor is an award presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS). It has been awarded since the 9th Academy Awards to an actor who has delivered an outstanding performance in a supporting role in a film released that year. The award is traditionally presented by the previous year's Best Supporting Actress winner. In lieu of the traditional Oscar statuette, supporting acting recipients were given plaques up until the 16th Academy Awards, when statuettes were awarded to each category instead.
