A writer has sued Taylor Sheridan, alleging he stole the idea for the hit series “Yellowstone.” The claim is brought in connection with a pitch the plaintiff says she made in 2016, according to reports.

Variety says the lawsuit was filed on Friday and lists additional defendants including 101 Studios, Paramount and Elevate Entertainment. The New York Post frames Sheridan’s “Yellowstone” as a long-running franchise that airs for five seasons from 2018 to 2024, noting the shows’ broader expansion into a larger television universe. Across the outlets, the central points are the alleged origin of the concept, the filing of a copyright-related case, and the fact that responses from Sheridan’s representatives and the other named companies were not immediately provided when contacted.

The reports do not agree on further details of the allegations or the specific legal theories beyond the theft claim, and no court outcome is described. The next procedural steps and any defenses are not yet reported.
