Sonic the Hedgehog 4 is racing to cinemas, at blue blur speed, folks. Sure, it'll still be awhile before the iconic Hedgehog actually arrives back on the big screen, but considering how good his previous three movies are, we aren't too fazed about the wait. As a massive fan of all the best Sonic games, and as a video game movie connoisseur, I'm especially excited for this upcoming movie and have been keeping a close eye on all the latest news and updates surrounding our speedy friend.
So far, we know that Sonic will be joined by Tails, Knuckles, and the rest of the gang for his next big-screen outing, and we know that Jeff Fowler is back in the director's chair, too. Even more casting announcements dropped in March as well, and speculation on possible new character reveals are buzzing through my brain as we speak. Basically, there's a lot to keep track of, and that's why I've made this guide to gather breakout insights from multiple interviews, juicy news and more.
If you want to learn about all the latest developments and everything else that you need to know about Sonic the Hedgehog 4, scroll on below. And once you are done getting your SEGA fix, have a look through the list of all the other upcoming video game movies currently in the works as well.
Sonic 4 release date
Sonic the Hedgehog 4 is due to hit theaters on March 19, 2027.
The news was confirmed just weeks after Sonic 3 sped into cinemas in December 2024. While its predecessor enjoyed a Christmas release, it seems the fourth installment is following in the white-sneakered footsteps of the second movie, which came out in spring (Sonic the Hedgehog dropped in February back in 2020).
Sonic 4 plot
While Paramount has not released an official synopsis at this time, Sonic fans have a few theories on what the fourth chapter might be about...
Sonic 3 ended with Team Sonic (Sonic, Tails, Knuckles, Tom, and Maddie) surviving, and Robotnik perishing in the explosion of the Eclipse Cannon. But the action didn't stop there. Not only does the Sonic 3 mid-credits scene introduce new character Amy Rose and a bunch of Metal Sonics, the post-credits scene confirms Shadow made it out of the final battle alive. While the snippet doesn't reveal Shadow's face, we'd recognize those shoes anywhere, and we see him retrieve one of his gold wrist cuffs from a crater.
With that, might Sonic 4 center on the spiky speedster's fight against the mechanical army? It seems safe to assume that Amy Rose will prove to be an ally, but what about Shadow? Despite being an antagonist for most of the third movie, Shadow wound up helping Sonic save the world at the end. Will he stick to being a do-gooder going forward?
Writers Pat Casey and Josh Miller previously told GamesRadar+ that Amy Rose almost had a bigger role in Sonic 3, beyond the mid-credits scene, and that they have a "great plan" for the future.
Then there's Robotnik. Leaked Sonic 3 concept art suggests that the movie was once going to feature a parallel universe or see the bald baddie use time travel. One image even shows Metal Sonic standing next to Emperor Eggman; might this be a storyline explored in Sonic 4 instead?
It's certainly possible, and follows the recent trend of Sonic movies being inspired by its video games. Sonic 3, of course, was a loose adaptation of Sonic 3. The inclusion of Metal Sonic may hint at the series closing in on Sonic CD territory. In the 1993 title, Sonic raced through various points in time to stop a 'bad future' ruled over by Eggman and his heavy, Metal Sonic.
Sonic 4 cast
Good news, we have a cast list for Sonic 4, and it's growing as well. Although with familiar faces we also have some new characters.
Check out Sonic 4 cast list below:
- Ben Schwartz as Sonic The Hedgehog

- Idris Elba as Knuckles
- Colleen O'Shaughnessey as Tails
- Kristen Bell as Amy

- Nick Offerman
- Richard Ayoade
As you can see from the above list, some characters are still undisclosed for now. We do know that Metal Sonic will appear at some point, and don't be surprised to see the usual post-credits scene spring a few new surprises and fresh faces, such as Rouge. Make sure to bookmark this tab to keep up with any cast announcements.
Is there a Sonic 4 trailer?
Unfortunately, there is no Sonic 4 trailer or even teaser at this point.
Paramount Pictures released the first full Sonic 3 trailer on August 27, 2024 – that's four months before the movie dropped. Based on those calculations, we can expect the Sonic 4 trailer sometime in late 2026 to early 2027. But we are secretly hoping to get at least a teaser a little sooner.
Will Sonic 4 be the last movie in the franchise?
There has been no confirmation on whether or not Sonic 4 will be the last movie in the Sonic movie franchise. However, in an interview with GamesRadar+, voice actor Schwartz said "We better do a thousand of these," in response to whether they’ll be more sonic movies.
Marsden added, "we hopefully get to keep making them". So who knows how many more Sonic movies are on the horizon?
