When plans to launch a second Star Trek television series in the late 1970s were scrapped by Paramount Pictures, the show's creator, Gene Roddenberry, instead transformed the aborted program's 2-hour pilot into this big budget theatrical feature. Five years after the legendary voyages of the starship Enterprise, James T. Kirk (William Shatner) is an unhappy, desk-bound admiral at Starfleet headquarters. Kirk goes aboard his old vessel to observe its re-launch under new captain Will Decker (Stephen Collins). Soon, however, an escalating crisis causes Kirk to take command of his old ship. A mysterious, planet-sized energy force of enormous power is headed for Earth. Reunited with Spock (Leonard Nimoy), Dr. Leonard "Bones" McCoy (DeForest Kelley), and the rest of his former colleagues, Kirk takes the Enterprise inside the massive energy cloud and discovers that it is the long-lost NASA space probe Voyager. Now a sentient being after accumulating centuries of knowledge in its deep space travels, the alien, which calls itself V'ger, has come home seeking its creator. Although not a critical home run, box office receipts for Star Trek: The Motion Picture (1979) were strong enough to inspire a revamped television series and a long-running line of theatrical sequels.
