Work has begun on the dubbing of "Sonic the Movie 4" - the film premiere will take place on March 19, 2027

Ben Schwartz, the voice of Sonic, announced that he’s begun recording lines for "Sonic the Hedgehog 4." Odd timing: principal photography wrapped a while back, yet the ADR (i.e., the voice-over work) is just getting underway now. Plot details remain under wraps — no leaks, no official synopsis. What is public: Keanu Reeves, Idris Elba, James Marsden and Jim Carrey are returning, and Ben Kingsley plus Nick Offerman will appear as well (e.g., additions to the cast list). The film’s worldwide premiere is slated for March 19, 2027.
