Twin brothers Matt and Ross Duffer are perhaps best known for their hit TV show Stranger Things on Netflix. Now, the brothers are branching out with new content for the network.

Netflix announced that it has signed the Duffer brothers to a "multi-year" deal that will see them create new movies and TV shows for Netflix. This is an "overall" deal, which means the Duffer brothers are working exclusively with Netflix, and the network may or may not own the IP rights to whatever the create for the streaming giant.

Netflix chief content officer Ted Sarandos said in a statement, "We're thrilled to expand our relationship with them to bring their vivid imaginations to other film and series projects our members will love."

He added: "We can't wait to see what The Duffer Brothers have in store when they step outside the world of The Upside Down."

The brothers, meanwhile, said they are "thrilled" to be working with Netflix on new shows and movies. The first of the new projects will be Stranger Things 4. The first teaser for the fourth season suggests the story may stray away from Hawkins, the town that has been the setting for the past three seasons. At the same time, the statement from the Duffer brothers specifically mentions that they are excited for their "return trip to Hawkins."

Before finding success with Stranger Things, the Duffer brothers sold a script for the post-apocalyptic horror movie Hidden to Warner Bros. Additionally, The Sixth Sense director M. Night Shyamalan brought on the brothers to write episodes of the show Wayward Pines.

Stranger Things was released in 2016 to much praise. A lawsuit that claimed the Duffer brothers stole the idea for Stranger Things was dropped just days before it was due to go to trial.
