Stranger Things is an American science fiction-horror web television series created, written, and directed by the Duffer Brothers and released on Netflix. The Duffer Brothers, Shawn Levy, and Dan Cohen serve as executive producers. The first season, released in July 2016, stars Winona Ryder, David Harbour, Finn Wolfhard, Millie Bobby Brown, Gaten Matarazzo, Caleb McLaughlin, Natalia Dyer, Charlie Heaton, Cara Buono, and Matthew Modine, with Noah Schnapp and Joe Keery in recurring roles. For the second season, Schnapp and Keery were cast as series regulars, along with the additions of Sadie Sink, Dacre Montgomery, Sean Astin, and Paul Reiser.
Set in the fictional town of Hawkins, Indiana, in the 1980s, the first season focuses on the investigation into the disappearance of a young boy amid supernatural events occurring around the town, including the appearance of a girl with psychokinetic abilities who helps the missing boy's friends in their own search. The second season, titled Stranger Things 2, is set one year later, and deals with attempts of the characters to return to normality and consequences that linger from the first season. The Duffer Brothers developed the series as a mix of investigative drama alongside supernatural elements portrayed with childlike sensibilities. They established its time frame in the 1980s and created an homage to the pop culture of that decade. Several themes and directorial aspects were inspired and aesthetically informed by the works of Steven Spielberg, John Carpenter, and Stephen King, among others, including several films, anime and video games.
