The official synopsis for the film is as follows:
Joker centres around the iconic arch nemesis and is an original, standalone fictional story not seen before on the big screen. Phillips’ exploration of Arthur Fleck, who is indelibly portrayed by Joaquin Phoenix, is of a man struggling to find his way in Gotham’s fractured society. A clown-for-hire by day, he aspires to be a stand-up comic at night…but finds the joke always seems to be on him. Caught in a cyclical existence between apathy and cruelty, Arthur makes one bad decision that brings about a chain reaction of escalating events in this gritty character study.
The film is directed by Todd Phillips and stars Joaquin Phoenix, Zazie Beetz, Robert De Niro, Frances Conroy, Marc Maron, Brett Cullen, Glenn Fleshler, Bill Camp, Dante Pereira-Olson, Douglas Hodge, Brian Tyree Henry, Shea Whigham and Bryan Callen.
Joker is scheduled for cinematic release on the 4th October 2019.
