Lightyear is a 2022 American computer-animated science fiction action-adventure film produced by Pixar Animation Studios and distributed by Walt Disney Studios Motion Pictures. The film is a spin-off of the Toy Story film series, serving as an origin story for the character Buzz Lightyear. It was co-written and directed by Angus MacLane and produced by Galyn Susman, and stars Chris Evans as the voice of the titular character, with Keke Palmer, Peter Sohn, Taika Waititi, Dale Soules, James Brolin, Uzo Aduba, Mary McDonald-Lewis, and Isiah Whitlock Jr. in supporting roles.

Lightyear tells the story of young astronaut Buzz Lightyear, who, after being marooned on a hostile planet with his commander and crew, tries to find a way back home while confronting a threat in the form of Zurg. Initially, the source material for Buzz Lightyear was introduced in the direct-to-video film Buzz Lightyear of Star Command: The Adventure Begins (2000), which was the pilot to a spin-off television series, Buzz Lightyear of Star Command (2000–2001). After finishing work on Finding Dory (2016), MacLane, a science fiction fan, pitched the idea of making a film about Buzz Lightyear at Pixar. To evoke the science fiction films he grew up watching, the animators wanted to give the film a "cinematic" and "chunky" look. Michael Giacchino composed the film's score.


Buzz Lightyear, a space ranger in Star Command, and his commanding officer and best friend, Alisha Hawthorne, explore the habitable planet, T'Kani Prime, with their new recruit, Featheringhamstan. They are forced to retreat to their exploration vessel after discovering that the planet hosts hostile lifeforms. Buzz damages the vessel during the retreat, forcing the crew to evacuate in order to conduct repairs and continue their journey.

One year later, the crew have constructed a nascent colony along with the necessary infrastructure to conduct repairs. Buzz volunteers to test hyperspace fuel, a key component of the repairs. However, after a four-minute test, he finds that four years have passed on T'Kani Prime, due to the effects of time dilation from having traveled at relativistic speeds. Buzz is introduced to Sox, a robotic feline, and continues testing the hyperspace fuel. With every test, four more years pass on T'Kani Prime, until eventually over 62 years have passed. During this time, the colony develops; Alisha raises a son with her wife Kiko, their son grows up, gets a promotion and gets married. Alisha subsequently dies of old age; and Sox improves the fuel's composition, allowing it to obtain faster-than-light speeds.

Against the orders of his new commanding officer, Commander Burnside, Buzz uses this new fuel composition for a successful hyperspace test. Upon landing, Buzz discovers 22 years have passed, during which T'Kani Prime has been invaded by Zyclops robots led by the mysterious Zurg. Buzz meets up with members of the colony’s defense forces, including Izzy Hawthorne, Alisha’s now-adult granddaughter; Mo Morrison, a fresh, naïve recruit; and Darby Steel, an elderly paroled convict. While initially reluctant to work with them, Buzz eventually warms to them. Together, they plan to attack Zurg’s ship and destroy the invading force.

Following an encounter, Zurg abducts Buzz, bringing him aboard his ship where he reveals that he is an older version of him from an alternate timeline in which, after the successful hyperspace test, Burnside attempted to arrest him for stealing the craft and forced him to escape. Aided by the effects of time dilation, he traveled to the far future, encountering a technologically advanced and abandoned vessel. He assumed Zurg's identity by wearing his signature mecha suit, and traveled to the now-present to obtain more hyperspace fuel from Buzz in order to travel further back in time and prevent the exploration vessel from landing on T'Kani Prime in the first place. However, Buzz refuses due to the implications of the possible temporal paradox that would result from such actions, which would wipe out the current timeline and everyone from it. Meanwhile, Izzy, Mo, Darby, and Sox board Zurg’s ship to assist Buzz. After a chaotic assault on the ship, Buzz and his comrades-in-arms destroy the ship and escape.

However, Zurg, having survived his ship's destruction, arrives and attacks Buzz, grabbing the hyperspace fuel. Buzz shoots the fuel, causing it to explode and incapacitate Zurg. With the fuel gone, Buzz wishes to stay on T'Kani Prime. Upon landing, Burnside arrests Buzz, but relents, allowing Buzz to revive the Space Ranger Corps. Buzz selects Izzy, Mo, Darby, and Sox to form the core of this organization, much to Burnside's surprise. Buzz and his team are then sent off to a new adventure in parts unknown. In a post-credits scene, a seemingly lifeless Zurg is floating in space when his eyes suddenly light up.
