The cast of Sonic the Hedgehog 2 features a talented roster of actors, both voice and live-action, with many of them very familiar thanks to roles in other great movies and TV shows. The film, directed by Jeff Fowler, received positive reviews and performed well at the box office after grossing over $405 million worldwide. Sonic the Hedgehog 2 followed immediately from the end of the first film, with Sonic trying his hand at vigilante hero work as the self-тιтled “Blue Justice.” However, he’s soon embroiled in a globe-trotting adventure with the return of Dr. Robotnik and the emergence of both new allies and enemies.

Two characters from the games, Knuckles the Echidna and Miles “Tails” Prower, are in Sonic 2, both CGI creations with voice-acting performances, similar to Sonic himself. The success of Sonic the Hedgehog 2 is helped in no small part by the seamless blend of the computer-generated elements of the film and the live-action performances. This is made possible by the excellent performances generated by the film’s voice actors.
