Gene Roddenberry's Utopian vision of humanity in the 24th century had a profound effect on American viewers. During the height of the Cold War, the tension of the civil rights movement and the jingoism of the Vietnam War, they saw a multicultural crew working together on the bridge of the Enterprise. Leonard Nimoy, Patrick Stewart, Nichelle Nicols, Brent Spiner and others reflect on Star Trek's cultural impact over its 30-year history, and contemplate its future on the small screen.
