Development
In 2013, Sony Pictures Entertainment acquired the rights to produce and distribute a Sonic film. On June 10, 2014, a live-action animated film was announced as a joint venture between Sony Pictures’ Columbia Pictures and Marza Animation Planet, a Japan-based subsidiary of Sega Sammy Holdings which had produced CGI cutscenes for several Sonic games. It would be produced by Neal H. Moritz by his Original Film banner alongside Takeshi Ito, Mie Onishi, and Toru Nakahara, and written by Evan Susser and Van Robichaux. In February 2016, Sega CEO Hajime Satomi said the film was scheduled for 2018. Blur Studio's Tim Miller and Jeff Fowler were hired in 2016 to develop it; Fowler would make his feature directorial debut, and Miller would serve as executive producer. Blur Studio previously produced cutscenes for the games Shadow the Hedgehog (2005), for which Fowler directed cutscenes, and Sonic the Hedgehog (2006). Patrick Casey, Josh Miller, and Oren Uziel were writing the screenplay, while Casey and Miller wrote the story.

On October 2, 2017, Paramount Pictures announced that they had acquired the rights after Sony put the film in turnaround. Almost all of the production team remained unchanged. In February 2018, it was announced that the film would be released in November 2019. During production the film used the working title "Casino Night", named after one of the stages in the Sonic games. Early drafts featured Sonic's Super Sonic form from the video games. The ideas were discarded as Fowler felt "it didn't make sense to obviously bring in the Super Sonic thing just yet” and wanted to focus on the origins of Sonic and Robotnik's relationship.

By 2022, Fowler announced plans for a Sonic Cinematic Universe, which kicked off in 2022 with Sonic the Hedgehog 2, where a third film and Knuckles tv series were announced ahead of thr film's release.
