Joaquin Phoenix

Most days, Arthur Fleck is bullied in public as he works as a clown-for-hire, but his slow descent into madness is hurried along by his mother's failing health, their strained connection with the rich Wayne family, and his failed comedy career.

A traumatized veteran, unafraid of violence, tracks down missing girls for a living. When a job spins out of control, Joe's nightmares overtake him as a conspiracy is uncovered leading to what may be his death trip or his awakening.
