Star Trek: The Motion Picture

Star Trek: The Motion Picture is a 1979 American science fiction film directed by Robert Wise. The Motion Picture is based on and stars the cast of the 1966–1969 television series Star Trek created by Gene Roddenberry, who serves as producer. In the film, set in the 2270s, a mysterious and powerful alien cloud known as V'Ger approaches Earth, destroying everything in its path. Admiral James T. Kirk (William Shatner) assumes command of the recently refitted Starship Enterprise to lead it on a mission to determine V'Ger's origins and save the planet.

When Star Trek was cancelled in 1969, Roddenberry lobbied Paramount Pictures to continue the franchise through a feature film. The success of the series in syndication convinced the studio to begin work on the film in 1975. A series of writers and scripts did not satisfy Paramount, and they scrapped the film project. Instead, Paramount planned on returning the franchise to its roots, with a new television series titled Star Trek: Phase II. The box office success of Star Wars and Close Encounters of the Third Kind convinced Paramount to change course, cancelling production of Phase II and resuming work on a film.

In March 1978, Paramount announced Wise would direct a $15 million film adaptation of the original television series. Filming began that August and concluded the following January. With the cancellation of Phase II, writers rushed to adapt its planned pilot episode, "In Thy Image", into a film script. Constant revisions to the story and the shooting script continued to the extent of hourly script updates on shooting dates. The Enterprise was modified inside and out, costume designer Robert Fletcher provided new uniforms, and production designer Harold Michelson fabricated new sets. Jerry Goldsmith composed the film's score, beginning an association with Star Trek that would continue until 2002. When the original contractors for the optical effects proved unable to complete their tasks in time, effects supervisor Douglas Trumbull was asked to meet the film's December 1979 release date. Wise took the just-completed film to its Washington, D.C., opening, but always felt that the final theatrical version was a rough cut of the film he wanted to make.

Released in North America on December 7, 1979, Star Trek: The Motion Picture received mixed reviews, many of which faulted it for a lack of action scenes and over-reliance on special effects. Its final production cost ballooned to approximately $44 million, and it earned $139 million worldwide, short of studio expectations but enough for Paramount to propose a less expensive sequel. Roddenberry was forced out of creative control for the sequel, Star Trek II: The Wrath of Khan (1982). In 2001, Wise oversaw a director's cut for a special DVD release of the film, with remastered audio, tightened and added scenes, and new computer-generated effects.

In the 23rd century, a Starfleet monitoring station, Epsilon Nine, detects an alien entity, hidden in a massive energy cloud, moving through space toward Earth. The cloud easily destroys three Klingon warships and Epsilon Nine on its course. At Earth, the starship Enterprise is undergoing a major refit; its former commanding officer, James T. Kirk, has been promoted to admiral. Starfleet Command assigns Enterprise to intercept the cloud entity, as the ship is the only one within range, requiring its new systems to be tested in transit.

Citing his experience, Kirk uses his authority to take command of the ship, angering Captain Willard Decker, who has been overseeing the refit as its new commanding officer. Testing of Enterprise's new systems goes poorly; two officers, including the ship's Vulcan science officer Sonak, are killed by a malfunctioning transporter, and improperly calibrated engines nearly destroy the ship. Kirk's unfamiliarity with the ship's new systems increases the tension between him and Decker, who has been temporarily demoted to commander and first officer. Commander Spock arrives as a replacement science officer, explaining that while on his home world, undergoing a ritual to purge himself of emotion, he felt a consciousness that he believes emanates from the cloud, making him unable to complete the ritual because his human half felt an emotional connection to it.

Enterprise intercepts the energy cloud and is attacked by an alien vessel. A probe appears on the bridge, attacks Spock, and abducts the navigator, Ilia. She is replaced by a robotic replica, sent by the entity, which calls itself "V'Ger", to study the "carbon units" on the ship. Decker is distraught over the loss of Ilia, with whom he had a romantic history, and becomes troubled as he attempts to extract information from the doppelgänger, which has Ilia's memories and feelings buried inside. Spock takes an unauthorized spacewalk to the vessel's interior and attempts a telepathic mind meld with it. In doing so, he learns that the entire vessel is V'Ger, a non-biological living machine.

At the center of the massive ship, V'Ger is revealed to be Voyager 6, a 20th-century NASA space probe from the Voyager program. It was believed lost in a black hole. The damaged probe was found by an alien race of living machines that interpreted its programming as instructions to learn all that can be learned and return that information to its creator. The machines upgraded the probe to fulfill its mission, and on its journey, the probe gathered so much knowledge that it achieved sentience. Spock discovers that V'Ger cannot give itself a purpose other than its original mission; having learned everything it could on its journey home, it finds its existence meaningless. Before transmitting all its information, V'Ger insists that the "Creator" come in person to finish the sequence. The Enterprise crew realizes humans are the Creator. Decker offers himself to V'Ger; he merges with the Ilia probe and V'Ger, creating a new life form that disappears into space. With Earth saved, Kirk directs Enterprise to space for future missions.
