2010: The Year We Make Contact (1984)

2010 (also known as 2010: The Year We Make Contact) is a 1984 American science fiction film written and directed by Peter Hyams. It is a sequel to the 1968 film 2001: A Space Odyssey, and is based on Arthur C. Clarke's novel 2010: Odyssey Two, a literary sequel to the film. Roy Scheider, Helen Mirren, Bob Balaban and John Lithgow star, along with Keir Dullea and Douglas Rain of the original cast.

Nine years earlier, the American Discovery One's mission to Jupiter mysteriously failed. As depicted in 2001: A Space Odyssey, Discovery's HAL 9000 computer—or "Hal" (Douglas Rain)—malfunctioned, killing four astronauts. The fifth, David Bowman, disappeared into a large, alien Monolith orbiting the planet. Bowman's last transmission before his disappearance was the cryptic line "My God! It's full of stars!" Back on Earth, Heywood Floyd (Roy Scheider), head of the National Council on Astronautics, received the blame for the failure and left the NCA. Since then he has been a teacher at a university. While diplomatic tensions are growing between the United States and the Soviet Union, both nations prepare space missions to determine what happened to the Discovery. Although the Soviet ship, the Alexei Leonov, will be ready before the American ship, the Soviets need American astronauts to help board the Discovery and investigate Hal's malfunction. The US government agrees to a joint mission since it has been determined that Discovery will crash into Jupiter's moon Io before its ship is ready. Floyd, along with Discovery designer Walter Curnow (John Lithgow) and HAL 9000's creator Dr. Chandra (Bob Balaban), join the Russian mission. Upon Leonov's arrival at Jupiter, captain Tanya Kirbuk (whose last name could be a reference to Stanley Kubrick) (Helen Mirren) and the other Soviets wake Floyd early from his hibernation because they have detected cholorophyll and other chemical signatures of life on Jupiter's frozen moon Europa. A burst of electromagnetic radiation destroys an unmanned probe from the Leonov as well as all telemetry data recorded by the probe. Floyd suspects that it is a warning to keep away from Europa. After surviving a dangerous aerobraking through Jupiter's atmosphere, the Leonov crew find the Discovery, abandoned but undamaged, orbiting the planet close to Io. Curnow reactivates the ship and Chandra restarts Hal, which Dave Bowman had deactivated shortly before he disappeared. Also close by is the alien Monolith that was the purpose of the Discovery mission. Cosmonaut Max Brailovsky (Elya Baskin) travels to the Monolith in an EVA pod, but is swept away by a burst of energy that emerges from the Monolith and heads to Earth; Max is never seen again. On Earth, Dave Bowman, now an incorporeal being but with all the memories of his former human self, appears on his widow's television screen and wishes her farewell. He also visits his terminally ill mother in a nursing home and combs her hair before she dies peacefully. Back on the Discovery, Chandra discovers the reason for Hal's malfunction: The NSC ordered the computer to conceal from Discovery's crew the fact that the mission was about the Monolith. This conflicted with Hal's basic function of open, accurate processing of information, causing him to suffer a mental breakdown. This was done without Floyd's knowledge, even though the order bears his signature, outraging Floyd. On Earth, tensions between the United States and Soviet Union escalate to what is "technically a state of war", and the US government orders Floyd, Curnow, and Chandra to move into Discovery. Both crews plan to leave Jupiter when a launch window opens in several weeks. However, Bowman appears and tells Floyd that everybody must leave Jupiter space within two days because "something wonderful" is going to happen. Floyd, shocked to the core by Bowman's appearance, returns to the Leonov to talk to Kirbuk, but then the Monolith suddenly disappears and a growing black spot appears on Jupiter itself. The spot is actually a vast group of Monoliths that are constantly multiplying. The Monoliths begin shrinking Jupiter's volume, increasing the planet's density, and modifying the chemical properties of its atmosphere. This convinces the two crews that they must leave soon. Since neither ship can reach Earth with an early departure, they work together to use the Discovery as a booster rocket for the Leonov. Tension arises when Hal is not told that the Discovery will be left stranded in space, and possibly destroyed, and Chandra fears that another deception may cause Hal to malfunction again. During the launch countdown, Chandra finally tells the computer the truth. Hal agrees that he must sacrifice itself for the human beings onboard Leonov to complete Discovery's mission, and thanks Chandra for telling him the truth. The Leonov leaves Jupiter just before the Monoliths engulf the planet and increase its density to the point that nuclear fusion occurs, transforming the planet into a small star. Bowman appears once again to Hal and tells him that their mission has been a success and repeats that "something wonderful" is going to happen. He commands Hal to break his communication link with the Leonov and repeatedly broadcast a final message to Earth: ALL THESE WORLDS ARE YOURS EXCEPT EUROPA ATTEMPT NO LANDING THERE USE THEM TOGETHER USE THEM IN PEACE The new star's miraculous appearance inspires the American and Soviet leaders to seek peace. Europa gradually transforms from an icy wasteland to a humid jungle covered with plant life. A Monolith stands in a swamp, waiting for intelligent life forms to come and find it.
