Voice cast  
 Ben Schwartz as Sonic the Hedgehog: A heroic yet overconfident anthropomorphic blue hedgehog who can run at supersonic speeds.

Idris Elba as Knuckles the Echidna: An anthropomorphic red echidna warrior with super strength. He is grumpy, serious, aggressive, and quick-tempered, but has a strong sense of honor. Shadow the Hedgehog, an anthropomorphic red-striped black hedgehog with Chaos energy powers, and the main result of "Project Shadow", is expected to have a major role in the film after making a silent cameo appearance in the mid-credit scene of Sonic the Hedgehog 2, where he was seen in a containment capsule waking up from suspended animation.

 James Marsden as Tom Wachowski, the town sheriff of Green Hills with whom Sonic, Tails and Knuckles live. Tika Sumpter as Maddie Wachowski, Tom's wife and a veterinarian with whom Sonic, Tails and Knuckles live. Natasha Rothwell as Rachel, Maddie's sister and Tom's sister-in-law. Adam Pally as Wade Whipple, Tom's friend and colleague and Knuckles' protege. Lee Majdoub as Agent Stone, an ex-government agent and Robotnik's assistant.

Development 
In February 2022, Sega Sammy Group and Paramount Pictures had been in development of a third Sonic the Hedgehog (2020) film after Sonic the Hedgehog 2 (2022). The film was formally announced during ViacomCBS's investor event, featuring much of the crew from the previous films. A series starring Knuckles the Echidna, who had appeared in Sonic the Hedgehog 2, for Paramount+, was being developed simultaneously with the film. Casting
On March 6, 2020, James Marsden confirmed that he had signed on for multiple sequels. In April 2022, Jim Carrey–who portrays Dr. Robotnik in the films–announced that he was considering retiring from acting. With his possible retirement, producers Neal H. Moritz and Toby Ascher confirmed that his role as Robotnik would not be recast in any sequels if he followed through with his retirement plans. However, they remained hopeful that they could develop scripts good enough for him to continue the role. Filming
Second-unit filming began in late July 2023 in Farnham, Surrey, England. Principal photography was originally scheduled to begin on August 31, 2023, in London, England, but was delayed to September of that year. Due to the 2023 SAG-AFTRA strike, scenes without actors would be shot first. Release 
Sonic the Hedgehog 3 will be released theatrically in the United States by Paramount Pictures on December 20, 2024. See also
