The teaser for the film, which stars Carrey as the computer-animated rodent's nemesis, Dr. Ivo "Eggman" Robotnik, was released in April, but devotees of the original SEGA console game expressed dismay at the character's looks, and the addition of human-like teeth in particular.
Following the controversy, Sonic's director Jeff Fowler, tweeted, "The message is loud and clear... you aren't happy with the design & you want changes. It's going to happen," and a new, cartoonish version was revealed in a second trailer last November (2019).
Speaking to Fox News, the star said of the controversy: "It turned out to be a co-op where everybody was in on the creation."
"I think everybody felt good about it ultimately because (director) Jeff Fowler (had) no ego involved at all. He just went, 'These people grew up with it, and it's important to them that we get it right.' And I think it was just a much better movie because of it."
The "Bruce Almighty" actor added that he doesn't create characters "based on what people are saying," but that he also felt elements of the film weren't "quite in the pocket" until being reworked.
"It was my concern, as well," he admitted. "(But) it turned out fantastic."
"Sonic the Hedgehog" is out now.
