The Trial of the Chicago 7: See How the Movie's Cast Compares to the Real People

Hoffman was a leading figure in the counterculture movement of the 1960s and '70s, founding the Youth International Party and being active in the "flower power" movement. He was also an antiwar activist during the Vietnam War era, with a particular knack for performance. In the years following the Chicago Seven trial, Hoffman became an even more controversial figure, writing books and continuing to protest — at one point, he was even arrested protesting the CIA's actions alongside President Carter's daughter Amy! He died by suicide in 1989.
