Once again, AMC is under fire from show creators due to its alleged questionable business practices.

“The Walking Dead” producers Gale Anne Hurd, Glen Mazzara, David Alpert and Robert Kirkman filed a lawsuit against AMC on Monday over profit sharing.
Kirkman also created the comic that inspired the show.

Reports from ComicBook.com state that the suit could become “one of the biggest profits cases in television history,” possibly leading up to $1 billion being sought in damages.

Producers of the hit TV show claim their shares of percentages of profits are being manipulated. The group is questioning the amount the network pays to its studio arm for the rights to air the show.

“There can be no question that, if AMC Studios and AMC Network were not part of the same conglomerate, the story would be very different,” the complaint reads, according to The Huffington Post.

The Hollywood Reporter notes that the complaint says that licensing fees for “The Walking Dead” are less than “Better Call Saul” and “Mad Men,” which are produced by non-affiliated companies while ratings for those shows are a fraction of “The Walking Dead’s.”

The producers claim that AMC “exploited their vertically integrated corporate structure to combine both the production and the exhibition of ‘The Walking Dead.’ This not only allowed AMC to keep a huge chunk of the series’ enormous profits for itself but also gave them the ability to not share it with the Plaintiffs, as required by their contracts.”

AMC told The Huffington Post the suit was “predictably opportunistic”.

Despite the lawsuit, the producers and AMC are still working on “The Walking Dead” and production is not expected to halt on the following season.
