Toy company Hasbro Inc. has filed a lawsuit against Sweetpea Entertainment, alleging that it has no right to make a new film based on the "Dungeons and Dragons" brand.
The reboot, penned by David Johnson ("Wrath of the Titans") is based on the obscure game "Chainmail" that D&D creator E. Gary Gygax developed first.
The lawsuit seeks an injunction to stop the project moving forward. Said project is currently in development at Warner Bros. Pictures, though Warners is NOT listed as a defendant.
They say Sweetpea Entertainment acquired the rights to "Dungeons & Dragons" in 1994 which were used to make the 2000 live-action feature. They also claim those rights have since reverted back to the toy company.
