General

 * Toy Story 4 will be the second Pixar film to be released on June 21, the first being Monsters University.
 * This is the first Toy Story film to be shot in the 2.35:1 aspect ratio, unlike the first three films of the franchise as they were produced in 16:9 ratio.
 * While the film was first officially announced in late 2014, John Lasseter and Andrew Stanton had started working on a treatment since 2012.
 * Lots-o'-Huggin' Bear, the main antagonist of Toy Story 3, was seen on stage at the 2015 D23 expo to promote Toy Story 4. Whether or not Lotso will be making an appearance in the film currently remains a mystery, considering that this film has been stated to be stand-alone from the original Toy Story trilogy.
 * Don Rickles, Mr. Potato Head's voice actor, passed away on April 6, 2017 before he could record any lines for the film. As such, with permission of Rickles' family, the film features Rickles' voice by using unused recordings from the first three films, from the video games and from Disney Parks.
 * John Lasseter was set to direct the fourth Toy Story film after directing both Toy Story and Toy Story 2. Lasseter left the direction of Toy Story 3 to Lee Unkrich while he directed Cars 2. However, Lasseter stepped down as director due to his busy schedule and later retired from both Pixar and Disney at the end of 2018, leaving Josh Cooley as the film's sole director in his directorial debut.
 * The bottoms of Woody's and Buzz's feet say "Bonnie" instead of "Andy", likely since Andy is no longer their owner.
