John Lasseter has said that Pixar would only make a fourth movie if it was just as good as or better than the previous three movies in the franchise, saying, "We don't want to do anything with [these characters] unless it lives up to or surpasses what's gone before."
The story for Toy Story 4 (2019) was created by John Lasseter, Andrew Stanton, Pete Docter, and Lee Unkrich. After they established a story outline for Toy Story 4 (2019), John Lasseter officially announced the project, saying, "Toy Story 3 (2010) ended Woody and Buzz's story with Andy so perfectly that for a long time, we never even talked about doing another Toy Story movie. But when Andrew, Pete, Lee, and I came up with this new idea, I just could not stop thinking about it. It was so exciting to me, I knew we had to make this movie - and I wanted to direct it myself."
In November 2018, Tom Hanks claimed that the ending was emotional and "a moment in history." He also added that he couldn't face the crew while recording his final lines because he got emotional with them. This came around 6 weeks after co-star Tim Allen said he couldn't get through the last few scenes because of how emotional they were.
Tom Hanks revealed on The Graham Norton Show (2007) that Disney executives forbade him to talk about this film before the film was officially announced by Walt Disney Pictures, because it could influence the stock market value of the company.
Each successive Toy Story movie is 11 minutes longer than its predecessor. The original is 81 minutes, the second film is 92, and the third is 103. It remains to be seen if this fourth film will be 114 minutes.
The Hollywood Reporter confirmed that Don Rickles had not recorded his dialogue for the character Mr Potato Head Toy Story 4 (2019) before he tragically passed away on April 6, 2017 due to kidney cancer. When the first teaser was shown on November 12, 2018, it was confirmed that Mr. Potato Head will indeed still be appearing with a new voice actor, but it was unconfirmed as to who it was at the time.
This will be the last role of Bud Luckey, who had passed away on February 24, 2018 at the age of 83 due to natural causes over a year before the film's release and this film was dedicated to his memory.
The Toy Story series has been referred to in both animated and live action movies. Finding Nemo (2003) (the dentist's office); The Shaggy Dog (2006) (dog jumps from bridge/car); Monsters, Inc.

Pixar initially had no plans to do a fourth film in the Franchise, with Toy Story 3 (2010) having been intent on being a closing point to the franchise with Andy saying goodbye to his toys.
