Michael Giacchino composed the film's score, while Ren Klyce served as its sound designer.

Development on Lightyear lasted for five and a half years, on an approximate $200 million budget. The team had brought two sets of lenses, two cameras, and a larger sensor equivalent to 65 millimeters, a procedure earlier initiated by Pixar in WALL-E (2008). To design the vehicles of the film, MacLane used Lego pieces to build various ships and pitch them to the designers and artists. The animators gave the film a 'cinematic' and 'chunky' look, evoking the science-fiction films MacLane grew up watching. The project was officially announced in an investor meeting held by Disney in December 2020. 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 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 then used as the pilot to the TV series Buzz Lightyear of Star Command (2000–2001). The film follows Buzz Lightyear (Evans) operating as a space ranger who, after being marooned on a hostile planet with his commander and crew, tries to find a way back home while encountering a threat to the universe's safety. It stars Chris Evans as the voice of the titular character, with Keke Palmer, Peter Sohn, Taika Waititi, Dale Soules, James Brolin, and Uzo Aduba in supporting roles. The film was directed by Angus MacLane (in his feature directorial debut) and produced by Galyn Susman, from a screenplay and story written by MacLane and Jason Headley, both of whom co-wrote the latter with Matthew Aldrich. Lightyear centers on the character Buzz Lightyear, who in this film is human and not a toy. The film is a spin-off of the Toy Story film series, but does not take place in the same fictional universe as them rather, it is presented as a film that some of the characters in the main Toy Story films have seen.

Lightyear is a 2022 American computer-animated science-fiction action-adventure film produced by Walt Disney Pictures and Pixar Animation Studios, and distributed by Walt Disney Studios Motion Pictures.
