Phoenix plays Arthur Fleck, a failed stand-up comedian whose fractured mental state and troubling encounters with the likes of Robert De Niro’s talk show host, Murray Franklin, leads him to a life of circus-inspired insanity in Gotham City.

The film also stars Brian Tyree Henry, Zazie Beetz, Frances Conroy and Marc Maron.

Joker is set for release on October 4th.
