Joker: Folie à Deux is the highly-anticipated follow-up to the 2019 blockbuster Joker, which saw Joaquin Phoenix deliver an Oscar-winning performance as Gotham’s most notorious villain. In the original film, Arthur Fleck, a mentally ill loner, embarks on a killing spree that culminates in the live murder of a talk show host—an act that triggers widespread chaos in Gotham.
The sequel takes place about two years after those events, centering on Arthur Fleck’s trial and his time in a correctional facility. Here, he crosses paths with Lee Quinzel (Lady Gaga), forming a twisted and dangerous bond.
