Sir Patrick Stewart, OBE (born 13 July 1940) is an English film, television and stage actor, who has had a distinguished career in theatre and television. He is most widely known for his television and film roles, such as Captain Jean-Luc Picard in Star Trek: The Next Generation and its successor films, Professor Charles Xavier in the X-Men film series, and as the voice of Avery Bullock in American Dad!.

Stewart was born on 13 July 1940 in Mirfield, near Dewsbury in the West Riding of Yorkshire, England. He is the son of Gladys (née Barrowclough), a weaver and textile worker, and Alfred Stewart, a Regimental Sergeant Major in the British Army who served with the King's Own Yorkshire Light Infantry and previously worked as a general labourer and as a postman.

In a 2008 interview, Stewart said: "My father was a very potent individual, a very powerful man who got what he wanted. It was said that when he strode onto the parade ground, birds stopped singing. It was many, many years before I realised how my father inserted himself into my work. I've grown a moustache for Macbeth. My father didn't have one, but when I looked in the mirror just before I went on stage I saw my father's face staring straight back at me."

Muhammad Ali (born Cassius Marcellus Clay, Jr.; January 17, 1942) is an American former professional boxer, philanthropist and social activist. Considered a cultural icon, Ali was both idolized and vilified.

Originally known as Cassius Clay, Ali changed his name after joining the Nation of Islam in 1964, subsequently converting to Sunni Islam in 1975, and more recently practicing Sufism.^{[clarification needed]} In 1967, three years after Ali had won the World Heavyweight Championship, he was publicly vilified for his refusal to be conscripted into the U.S. military, based on his religious beliefs and opposition to the Vietnam War. Ali stated, "I ain't got no quarrel with them Viet Cong... No Viet Cong ever called me nigger" – one of the more telling remarks of the era.

Widespread protests against the Vietnam War had not yet begun, but with that one phrase, Ali articulated the reason to oppose the war for a generation of young Americans, and his words served as a touchstone for the racial and antiwar upheavals that would rock the 1960s. Ali's example inspired Martin Luther King Jr. – who had been reluctant to alienate the Johnson Administration and its support of the civil rights agenda – to voice his own opposition to the war for the first time.

Joseph William "Joe" Frazier (January 12, 1944 – November 7, 2011), also known as Smokin' Joe, was an American professional boxer and Olympic and Undisputed World Heavyweight Champion, whose professional career lasted from 1965 to 1976, with a one-fight comeback in 1981.

Frazier emerged as the top contender in the late 1960s, defeating opponents that included Jerry Quarry, Oscar Bonavena, Buster Mathis, Eddie Machen, Doug Jones, George Chuvalo and Jimmy Ellis en route to becoming Undisputed Heavyweight Champion in 1970, and followed up by defeating Muhammad Ali on points in the highly-anticipated "Fight of the Century" in 1971. Two years later Frazier lost his title when he was knocked out by George Foreman. He fought on, beating Joe Bugner, losing a rematch to Ali and beating Quarry and Ellis again.

Frazier's last world title challenge came in 1975, but he was beaten by Ali in their brutal rubbermatch. He retired in 1976 following a second loss to Foreman. He made a comeback in 1981, fighting just once, before retiring for good. The International Boxing Research Organization (IBRO) rates Frazier among the ten greatest heavyweights of all time. He was an inductee of both the International Boxing Hall of Fame and the World Boxing Hall of Fame.
