Ben Schwartz: Voice Recording Underway for Sonic the Hedgehog 4

Ben Schwartz confirmed on X that studio voice recording sessions for Sonic the Hedgehog 4 have begun. He posted the update after production sources reported that live-action filming wrapped earlier this month. The film is scheduled to open worldwide on March 19, 2027.

The sessions mark the start of actor-driven audio work for the project. Performers are recording dialogue tracks that will be synced with visual effects, edited footage and final sound mixing as the production moves through post-production.

Schwartz, who returns as the voice of Sonic in the current film series, did not include locations, clips or further casting information in the post. The studio has not published a detailed timeline for post-production milestones or announced additional recording dates.

With principal photography complete and voice work underway, the crew will continue to advance visual effects, editing and final audio tasks ahead of the March release date. Studio representatives have not issued further comments on the production schedule or promotional plans.

Further announcements about casting, trailers and premiere events are expected as the film progresses through post-production.
