It does seem as though this particular Sonic the Hedgehog movie will make use of both computer animation as well as live action, which might make it end up like the Smurf movies that we have seen in recent times. Such speculation would make sense, considering how the Smurfs movies were produced by Sony as well.
Hannah Minghella, president of production at Sony’s Columbia Pictures, shared, “There are limitless stories to tell with a character like Sonic the Hedgehog and a built-in international fan base. Along with our wonderful creative partners at Marza, we’re looking to capture everything that generations of fans know and love about Sonic while also growing his audience wider than ever before.”
Possible plots could revolve around Dr Robotnik, Sonic’s eternal nemesis, and we might also catch glimpses of other characters such as Tails his sidekick.
