Currently, plot and character details for Sonic the Hedgehog 3 are slim. However, the movie is expected to pick up from the cliffhanger ending of the sequel and introduce a new villain in the form of the notorious Shadow. Since Carrey has retired from acting, he is not expected to return as Dr. Robotnik, although the filmmakers have decided not to recast his character. Schwartz previously teased that the film is "going to be bananas," with subsequent details indicating that Sonic the Hedgehog 3 will include elements from the video games Sonic Adventure 2 and Shadow the Hedgehog. Details on Sonic the Hedgehog 3 have been scant since, although now there is a major update.
As confirmed by Sonic the Hedgehog's official social media, the threequel has been scheduled to premiere on December 20, 2024. No further details have been revealed, but it's nevertheless reassuring to know that the movie has managed to secure an auspicious holiday release window. Take a look at the tweet below.
The new release date for Sonic the Hedgehog 3 continues the trend of leaving two years between movies in the franchise, so all installments will hopefully feel evenly spaced out. Right now, the date confirmation doesn't give much of an idea about the movie's story, although it indicates that a similar announcement could arrive soon for the Knuckles spinoff, which will see Elba reprising his red echidna role. The Knuckles show will set up Sonic 3, so it seems likely that the project will start to move forward now that the movie has a release date. There is plenty of room for both over the next two years.
Now the question of how Sonic the Hedgehog 3 will resolve some of its most pressing dilemmas remains. The immediate task the movie needs to take care of is addressing Carrey's potential exit and explaining how the threequel will handle Dr. Robotnik's absence. In the games, Dr. Robotnik had a crucial role in bringing his grandfather's Project Shadow to life and provoking the conflict between Sonic and Shadow. However, with Robotnik presumably not returning for Sonic the Hedgehog 3, the movie might choose to tweak Shadow's backstory, associating him with Guardian Units of Nations (G.U.N.) instead of Robotnik. Additionally, with a premiere date set, Sonic 3 could also reveal other game characters that might show up in the film. That said, with a release in sight, audiences can expectmore exciting updates from Sonic the Hedgehog 3 in the coming months.
