Reference excerpt

Lightyear is a 2022 American animated science fiction action film produced by Pixar Animation Studios for Walt Disney Pictures, and starring Chris Evans as the voice of Buzz Lightyear. Presented as a film within a film, Lightyear is a spin-off of the Toy Story film series and centers on the character Buzz Lightyear, who appears in Toy Story as an action figure of his character in Lightyear. The film was directed by Angus MacLane and written by MacLane and Jason Headley. Besides Evans, Keke Palmer, Peter Sohn, Taika Waititi, Dale Soules, James Brolin, and Uzo Aduba voice supporting roles. The film follows Buzz who, after being marooned on the hostile planet T'Kani Prime with his commander and crew, tries to find a way back home while encountering a threat to their safety. The concept of a human Buzz Lightyear, who exists in a fictional universe within a fictional universe, was first introduced in the 2000 direct-to-video film Buzz Lightyear of Star Command: The Adventure Begins, which was the pilot for the TV series Buzz Lightyear of Star Command (2000–2001). MacLane, an avid science-fiction fan, pitched the idea of a film featuring Buzz Lightyear at Pixar, after finishing work on Finding Dory (2016). The project was officially announced in an investor meeting held by Disney in December 2020. The animators gave the film a "cinematic" and "chunky" look, evoking the science-fiction films MacLane grew up watching. To design the vehicles of the film, MacLane used Lego pieces to build various ships and pitch them to the designers and artists. For its IMAX scenes, the team used two virtual cameras, a regular camera with a 35mm equivalent sensor, and a larger sensor equivalent to 65 millimeters, a procedure earlier initiated by Pixar in WALL-E (2008). Development on Lightyear lasted for five and a half years. Michael Giacchino composed the film's score, while Ren Klyce served as its sound designer. Lightyear premiered at the El Capitan Theatre in Hollywood, Los Angeles, on June 8, 2022, and was theatrically released in the United States on June 17. It became the first Pixar film to be released in theaters worldwide since Onward in March 2020, and the first to include scenes specifically formatted for IMAX theaters. The film received generally positive reviews from critics and was considered by analysts to be a box-office bomb, as it grossed $226.4 million worldwide against an approximate $200 million budget, losing the studio an estimated $106 million.

Plot

A Star Command exploration vessel filled with hypersleeping personnel changes course to investigate signs of life on the unknown world T'Kani Prime. Awakened from hibernation by the ship AI, Space Ranger Buzz Lightyear and his commanding officer and best friend Alisha Hawthorne explore the planet with a new recruit in tow. They are forced to retreat to their exploration vessel after discovering that the planet hosts hostile lifeforms. While attempting to leave, Buzz accidentally damages their vessel, causing them and their many shipmates to be marooned on T'Kani Prime. After surveying the damage, they find that the fuel for the ship was destroyed. Buzz volunteers to be the test pilot for the hyperspace fuel crystal they will need to develop to power the ship home. One year later, the crew has constructed a colony to extract resources from the planet and conduct repairs. However, after a four-minute test flight, Buzz finds that four years have passed on T'Kani Prime due to the effects of time dilation from travelling at relativistic speeds. Alisha gifts Buzz with Sox, a robotic feline companion, and Buzz decides to continue testing the hyperspace fuel. With every test, four more years pass on T'Kani Prime, until eventually over 66 years have passed. During this time, the colony develops, with Alisha raising a son with her wife Kiko, subsequently dying of old age, while Sox improves the fuel's composition, allowing the ship to obtain faster-than-light speeds. Against the orders of Alisha's successor Commander Cal Burnside, Buzz, accompanied by Sox, uses the new fuel composition for a successful hyperspace test. However, he and Sox skip 22 years into the future during which T'Kani Prime has been invaded by Zyclops robots led by Zurg, the robots' commander. Buzz and Sox meet up with members of the colony's defense forces: Alisha's now-adult granddaughter Izzy Hawthorne; 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 after they escape from a nest of insects and investigate a mining facility to repair their ship. Together, they plan to destroy the invading force at Zurg's mothership. As they head back to the ship, Zurg intervenes and captures Buzz, then reveals himself to be an older version of Buzz from an alternate timeline, which split upon Buzz's return to the planet after the successful hyperspace test: soldiers from the colony attempted to arrest him under Burnside's orders, forcing him to flee into space. This Buzz and his Sox escaped at full speed and, via time dilation, flew hundreds of years into the far future, where he encountered and stole extremely advanced technology, and eventually developed a way to travel back in time to prevent himself from stranding the Star Command crew upon the planet. Having worn out his own fuel, Zurg needs fresh fuel to travel further into the past and complete his mission, so he requests it from his younger self. Realizing this would erase Alisha and Kiko's life together, along with Izzy and the lives of all the other colonists, Buzz refuses. Aided by Zurg's Sox, Buzz and the cadets escape Zurg's ship and set it to self-destruct. On their return to the planet via a crash landing, Zurg attacks and takes the fuel for himself. Buzz ejects to shoot the fuel, causing an explosion that kills Zurg. With the fuel gone, Buzz finally accepts T'Kani Prime as his home. Burnside arrests the group with the intention of detaining them for their actions, but relents in light of Buzz's bravery against the robot armada. Allowed to revive the Space Ranger Corps, Buzz selects Izzy, Mo, Darby, and Sox as his team. With a new fuel crystal, Buzz and his team embark on a mission to investigate an unknown signal from the Gamma Quadrant of Sector 4.

Worked examples

Example 1 — a first encounter with Lightyear (film)

Start with the simplest possible case. Write down what Lightyear (film) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lightyear (film) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lightyear (film) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lightyear (film)

In research
Lightyear (film) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lightyear (film) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lightyear (film) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020s animated superhero films, 2020s films about time travel, 2020s science fiction adventure films, so understanding it makes those chapters shorter.
In everyday life
Look for Lightyear (film) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
