This film is a grand masterpiece filled with philosophical themes that Kubrick spent four years making. A large black monolith stands before prehistoric humans, who have just begun to recognize tools, marking a milestone in evolution. The same black monolith appears in various places in the universe, standing on the moon and floating in space, carrying a certain mysterious meaning. The current time is 2001, and to find the origins of the monolith, humanity has launched a Jupiter landing mission. On the spacecraft are three hibernating astronauts: Captain David (played by Keir Dullea), pilot Frank (played by Gary Lockwood), and a highly intelligent computer called 'HAL 9000.' During the space flight, HAL malfunctions, resulting in the deaths of Frank and the three hibernating crew members, leaving Bowman to battle against the computer. After returning from the brink of death, David, in anger, shuts down the central computer system, and HAL is rendered completely inoperative. Now, in the vast universe, there is only David left, heading towards Jupiter. Passing through the bizarre and magnificent Stargate, David seems to enter a peculiar space-time where there is the endless cycle of life and death of humanity and the ultimate knowledge of the universe...
