 Nicholas Kulish, The New York Times ; Is ‘The Pitt’ Really an ‘ER’ Spinoff? Michael Crichton’s Estate Says It Is.

The estate of the best-selling author, which has intellectual property rights to “ER,” and the creators of the new hit TV show are waging a legal battle over whether it’s a stealth reboot.

“‘The Pitt’ has no connection to ‘ER’ — it does not use ‘ER’’s intellectual property, characters, plot, setting or narrative pacing,” the defendants said. “While both series are medical dramas set in a hospital, this concept is hardly unique.” They name-checked “Grey’s Anatomy,” “Chicago Med,” “House” and “The Good Doctor.”...

The case “could serve as a model for how to figure out how much things are worth in the streaming space,” said Jennifer Porst, a professor of media industry studies at Emory University in Atlanta."
