As TMZ reports, writer Charlie Kessler has filed a lawsuit, claiming the Duffer brothers ripped the plot of Stranger Things from his short film Montauk, which premiered in 2012 and involved “top secret government experiments,” similar to the plot of Stranger Things.

Kessler says he and his agents pitched the concept to the Duffer Brothers in April 2014 “as a full-blown series,” but the Duffer brothers had not contacted him to pursue the idea any further.

He says he was “shocked” when Stranger Things debuted in July 2016 and claim the brothers used his “script, idea, story and film” to make the hit show.

Plus, he also notes that the show was initially sold to Netflix with the name of his short film: “The Montauk Project.”

TMZ reports that Kessler is asking for “money and destruction of all materials that were allegedly ripped off from his concept.”

The Duffer Brothers and Netflix have yet to respond to Kessler's claims.
