WATCH: Trailer for new Netflix sci-fi series "Maniac" enthrallsThe first trailer for Netflix’s intriguing new sci-fi dark comedy series, Maniac, has just been unveiled. And if it looks like deft hands worked on it, it’s because it’s true. The Leftovers-producer/writer, Patrick Somerville, and True Detective-director, Cary Fukunaga, have banded together to make what looks like a promising piece of television.

As of press time, plot details are scarce, but we do know that it’s loosely based on a Norwegian series of the same-name, and that is about a thirtysomething man caught in the prison of his own mind as well as a high-level psychiatric facility. In the Netflix version, that man is played by Jonah Hill, who takes a shine on a fellow patient, played by Emma Stone.

The trailer teases a few of Espen’s outings split from reality: we see Tolkien-esque adventures, Jazz-age assemblages, and more.

Maniac casts Leftovers-alum Justin Theroux as the facility’s assertive and morally ambiguous head scientist, and Sonoya Mizuno—who’s set to also star in Alex Garland’s upcoming FX series, Devs—as his trusty partner, Dr. Fujita. Sally Field, Jemima Kirke, Julia Garner, and Billy Magnussen also star.

The series is set to premiere on Netflix on September 21st.
