Claim: Christopher Reeve (an American actor, director, and activist, best known for playing the title role in the film Superman (1978) and its three sequels), once a Williamstown Theatre Festival apprentice and later a frequently-featured actor there, told an interviewer: "By staying here thirty years, Nikos [did] what they couldn't do in Brooklyn or Washington or at Lincoln Center" about Nikos' work at the theater (where he mentored his associates and assistant directors).
Evidence: Christopher D'Olier Reeve (September 25, 1952 – October 10, 2004) was an American actor, director, and activist, best known for playing the title role in the film Superman (1978) and its three sequels. In mid-1968, at age fifteen, Reeve was accepted as an apprentice at the Williamstown Theatre Festival in Williamstown, Massachusetts. Nikos Psacharopoulos, a professor at Yale Drama School and a co-founder, became the executive artistic director and guided the company for over thirty years. Christopher Reeve, once a WTF apprentice and later a frequently-featured actor at the festival, told an interviewer: "By staying here thirty years, Nikos [did] what they couldn't do in Brooklyn or Washington or at Lincoln Center. He has managed to achieve a national theater." Psacharopoulos made certain WTF would not be a typical summer stock theater by focusing on such international playwrights as Chekhov, George Bernard Shaw, Jean Anouilh, Tennessee Williams, Bertholt Brecht, and Tom Stoppard. He mentored his associates and assistant directors, such as Tom Brennan, Arvin Brown, Keith Fowler, Peter H. Hunt, Paul Weidner, and Austin Pendleton.
