Emma Stone and Jonah Hill, who became stars after appearing together in the 2007 movie Superbad, will reunite for a dark comedy series called Maniac, to be directed by True Detective Season 1 and Beasts of No Nation helmer Cary Fukunaga, Deadline reports.

The series, which is based on a 2014 Norwegian program, is about a man who has fantastical adventures in his dreams but in reality is locked up in a mental institution. Hill and Stone will both play patients in the the institution.

Fukunaga is slated to direct all episodes, as he did with True Detective's first season.

Maniac is currently in very early stages of development. Stone and Hill—both Oscar-nominated actors these days—are finalizing deals, and the project does not currently have a writer. No network is attached, but producers are reportedly shopping it to cable channels and streaming platforms and looking for a straight-to-series order.

This will be the first starring TV role for both Stone and Hill.
