Sonic the Hedgehog 3 is an 2024 action-adventure comedy film based on the video game series published by Sega and the sequel to Sonic the Hedgehog (2020) and Sonic the Hedgehog 2 (2022). It is directed by Jeff Fowler and stars James Marsden, Ben Schwartz, Tika Sumpter, Colleen O'Shaughnessey, Lee Majdoub, Idris Elba, and Jim Carrey, who reprise their roles from previous installments. Plans for a third Sonic the Hedgehog film were announced in February 2022 during ViacomCBS's investor event before the release of the second film. Due to the 2023 SAG-AFTRA strike, filming for animated characters began in July 2023 in Surrey, England, while filming with physical actors began in November of that year in London, with production concluding by March 2024. The film will draw inspiration from the video games Sonic Adventure 2 (2001) and Shadow the Hedgehog (2005). Sonic the Hedgehog 3 is scheduled to be theatrically released by Paramount Pictures in the United States on December 20, 2024.
