2019 Synopsis
Director Todd Phillip’s “Joker” centers 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 Joaquin Phoenix indelibly portrays, 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.
