Joker: Folie à Deux is set to release on October 4, 2024. Directed by Todd Phillips, the sequel to the 2019 Joker follows Arthur Fleck’s further descent into madness. The title, meaning "madness shared by two," suggests a focus on the relationship between Arthur and Harley Quinn, played by Lady Gaga. The film will feature musical elements, distinguishing it from the first movie.

Plot details remain under wraps, but it will likely explore mental illness, shared delusion, and toxic relationships in Gotham’s dark, chaotic world.
