Considered a landmark film, Stanley Kubrick's 1968 science-fiction epic "2001: A Space" Odyssey" took viewers on a wild ride through time and space, tracing man's destiny. With only 40 minutes of actors' dialogue in the 140-minute film, visionary filmmaker Kubrick used music to create suspense and intrigue. Rather than composing a new score, Kubrick chose classical pieces for the film. Johann Strauss' "The Blue Danube" and Richard Strauss' "Also Sprach Zarathustra" make the soundtrack one of the most recognizable in cinematic history. The music, combined with cutting-edge visual effects, resulted in a trippy atmosphere, thrusting the film into the world of the 1960s drug counterculture. Popular with younger audiences in the era of the Vietnam War, the thought-provoking film appealed to their inclination to question authority. Billed as "the ultimate trip," "2001" became one of year's most critically acclaimed films and an enduring classic.
