The Duffer Brothers

Matt Duffer and Ross Duffer (born February 15, 1984), often credited as the Duffer Brothers, are both American writers, directors, and producers. The brothers are identical twins and work on all their projects as a pair. They are best known as the creators, directors, and executive producers of the Netflix science fiction horror series Stranger Things (2016–2025), and have also written and directed the horror film Hidden (2015) and written and produced episodes of the Fox science fiction series Wayward Pines (2015–2016). The Duffer Brothers founded the production company Upside Down Pictures, which is in an overall deal with Netflix.

After the brothers had written and directed several short films, they wrote a script titled "Origin", which gained them an agent, and their script for the post-apocalyptic horror film Hidden was acquired by Warner Bros. Pictures in 2011. The brothers directed Hidden, which was released in 2015. Next they were hired as writers and producers for the Fox television series Wayward Pines. As of 2024, they were also the executive producers of a Netflix show called The Boroughs, described as a supernatural drama set in a retirement community in the New Mexico desert.

With experience in television, they began pitching their idea for Stranger Things, which Dan Cohen eventually brought to Shawn Levy. Backed by Levy's 21 Laps production company, the show was quickly picked up by Netflix. The show is set in 1980s Indiana and is an homage to 1980s pop culture, inspired and aesthetically informed by the works of Steven Spielberg, John Carpenter, Wes Craven, Sam Raimi, David Lynch, Stephen King, and George Lucas, among others.

It was released on July 15, 2016, to overwhelming praise, specifically for its characterization, pacing, atmosphere, acting, soundtrack, directing, writing, and homages to 1980s genre films. It began to develop a cult following online. Review aggregator Rotten Tomatoes gave the series an approval rating of 92%, based on 82 reviews, with a weighted average score of 7.96/10. The site's critical consensus states, "Exciting, heartbreaking, and sometimes scary, Stranger Things acts as an addictive homage to Spielberg films and vintage 1980s television."

On September 30, 2019, Netflix announced it had signed the Duffers for additional films and television shows over the coming years.

In March 2021, the duo announced they will team up with Spielberg to adapt Stephen King's and Peter Straub's The Talisman as a Netflix series. They will both be executive producers via Amblin Partners and Monkey Massacre and have hired Curtis Gwinn, who worked as a writer-executive producer on Stranger Things, to act as writer and showrunner of the project.

Following the premiere of the fourth season of Stranger Things in July 2022, the Duffers launched the production company Upside Down Pictures, for which they recommitted to Netflix with several new projects. Among these include a live-action series adaptation of Death Note and a series adaptation of The Talisman, in addition to their follow-up series to Stranger Things.

In October 2023, Ross Duffer was one of many working in the film and television industry that signed the open letter to President Joe Biden thanking him for his "unshakeable moral conviction" in supporting Israel with military funding and aid and petitioning the President to secure the release of more Israeli hostages.
