Sonic the Hedgehog 3 is poised to become the most successful installment of the Sonic franchise, so it’s no wonder that a fourth movie featuring the bright blue speedster and his equally colorful friends has already been greenlit by Paramount Pictures. Although few details have been revealed about the upcoming film, Jim Carrey — who plays Sonic’s iconic arch-nemesis, Dr. Ivo Robotnik — may end up reprising his fan-favorite role, despite his hints at a well-deserved retirement from Hollywood sometime in the near future.
