Maniac is an American black psychological comedy drama television miniseries that premiered on Netflix on September 21, 2018, after being announced in 2016. Patrick Somerville created the series and Cary Joji Fukunaga directed, basing it very loosely on the 2015 Norwegian television series of the same name while drawing inspiration from many more famous films. The 10-episode series stars Emma Stone, Jonah Hill, Justin Theroux, Sonoya Mizuno, Gabriel Byrne, and Sally Field. The plot follows two strangers who connect during a mind-bending pharmaceutical trial set in a retro-future New York City.
