Set in a crime-ridden Gotham City sometime in the early 1980s, Joaquin Phoenix stars as Arthur Fleck, a man who has been dealing with mental challenges his entire life, with little to show for all of his efforts to keep on the sane path. One of his afflictions is his uncontrollable laughter when faced with things that make him anxious, which often gets him into further trouble on its own. He’s living in a Gotham City apartment with his ailing mother, Penny (Frances Conroy), trying to make it on his own either as a clown or as a stand-up comedian, on the hope of getting on the number-one late-night talk show starring Murray Franklin (Robert De Niro). Even with the several medications that he is on, his afflictions often get the better of him, but now he’s lost his job, his therapist, his meds, and his sanity, but finds there may be a new path to an audience when he gains notoriety as a Bernard Goetz-style subway shooter. Directed and co-written by Todd Phillips.
