The next big video game movie on the horizon is Sonic the Hedgehog 2. Although it's not out until next year, we seem to be learning more and more about it each week.

Just last week, the film's director Jeff Fowler revealed how production had already wrapped up in Canada, and now it seems the synopsis for the second movie has now been revealed via copyright from Paramount Pictures and Sega.

Here are the full details (warning - potential spoilers ahead):

"After settling in Green Hills, Sonic is ready for more freedom, and Tom and Maddie agree to leave him home while they go on vacation. But, no sooner are they gone, when Dr. Robotnik comes back, this time with a new partner, Knuckles, in search for an emerald that has the power to both build and destroy civilizations. Sonic teams up with his own sidekick, Tails, and together they embark on a journey to find the emerald before it falls into the wrong hands. Being directed by Jeff Fowler, and starring Jim Carrey, James Marsden, and Ben Schwartz."

As you see, the synopsis name drops both Tails and Knuckles, and obviously confirms the return of characters like Sonic and Dr. Robotnik. If you saw the first movie, you might recall how Sonic's sidekick showed up at the very end of the movie, and last month, a Knuckles prop was spotted on Sonic 2's film set.
