Is ‘The Walking Dead’ falling apart behind the scenes?

CLEVELAND, Ohio – On the upcoming eighth season of AMC’s “The Walking Dead,” the main characters will unite like never before against a common enemy. However, behind the scenes, cable’s top series couldn’t be more divided.

“The Walking Dead” comic book creator Robert Kirkman has joined executive producers Glen Mazzara (also a former showrunner), David Alpert and Gale Anne Hurd in a lawsuit against AMC.

The four parties are alleging that AMC – through “The Walking Dead,” “Talking Dead” and “Fear the Walking Dead” — violated terms of their business deals. Kirkman and company said they are owed profits that were withheld due to alleged shady corporate maneuvering.

For his part, Kirkman recently parted ways with AMC, signing a new production deal with Amazon Studios. Kirkman’s company Skybound will partner with the streaming service on new projects (“The Walking Dead” franchise still belongs to AMC).

“The defendant AMC Entities exploited their vertically integrated corporate structure to combine both the production and the exhibition of “TWD” which allowed AMC to keep the lion’s share of the series’ enormous profits for itself and not share it with the Plaintiffs, as required by their contracts,” the lawsuit claims.

This isn’t the first time AMC has been sued over “The Walking Dead.” Original showrunner Frank Darabont has been embattled in a three-year long lawsuit claiming the network owes Darabont and Creative Artists Agency close to $300 million.

As with the Darabont lawsuit, AMC dismissed Kirkman, Hurd, Mazzara and Alpert’s claims as invalid and called the lawsuit “opportunistic.”

Regardless, “The Walking Dead” Season 8 will premiere on Oct. 22 on AMC.
