Video game publisher Activision Blizzard formally sued game developer Double Fine Studios on Wednesday. The point of contention? Tim Schafer's Brutal Legend, the Xbox 360/PlayStation 3 game starring Jack Black.

Activision Blizzard claims that it still has a valid contract for the title, and had invested roughly $15 million in the game. The lawsuit issued by Activision Blizzard states that Double Fine transferred rights that were owned by the company to the now-current publisher Electronic Arts.

The Associated Press attempted to contact both Double Fine and Electronic Arts, but received no response.
