The Sonic the Hedgehog movie sequel will release April 2022
The Sonic the Hedgehog movie is the little film that could. Following the initial announcement and its uncanny valley CGI Sonic, the movie revamped Sonic's design into one that fans much preferred, and after a slight delay, it managed to finally release in theaters earlier this year, surpassing Detective Pikachu as the most successful video game movie opening of all time. It took three months after its launch for Paramount to greenlight a sequel, which now has a release date. Movie Sonic's voice actor, Ben Schwartz confirmed that "Sonic 2" would be making its way to theaters on April 8, 2022. The same team who worked on "Sonic the Hedgehog" will return again to pen the script, and with Schwartz's involvement, it's likely we'll see some of the acting cast return as well.
