Directed by Jeff Fowler, Sonic the Hedgehog 2 is the action-adventure comedy film based on the video game franchise published by Sega, and the sequel to Sonic the Hedgehog (2020). Ben Schwartz reprises his role as the voice of Sonic the Hedgehog, alongside a majority of the returning cast from the first film, including James Marsden. After settling in Green Hills, Sonic the Hedgehog is eager to prove he has what it takes to be a true hero. His test comes when Dr. Robotnik (Jim Carrey) returns, this time with a new partner, Knuckles the Echidna (Idris Elba), in search for an emerald that has the power to destroy civilizations. Sonic teams up with his own sidekick, Tails (Colleen O’Shaughnessey), and together they embark on a globe-trotting journey to find the Master Emerald before it falls into the wrong hands, while also contending with the military organisation G.U.N.
