Joker: Folie à Deux is an upcoming American musical film directed by Todd Phillips from a screenplay he co-wrote with Scott Silver. Produced by Warner Bros. Pictures, Village Roadshow Pictures, DC Studios, Bron Creative, and Joint Effort, and distributed by Warner Bros. Pictures, the film is based on the Joker and other characters appearing in DC Comics publications, serving as the sequel to Joker (2019).
The stars who have been confirmed for the upcoming movie are:
Joaquin Phoenix as Arthur Fleck / Joker: A mentally ill, impoverished party clown and stand-up comedian disregarded by society, whose history of abuse causes him to become a nihilistic criminal with a clown motif.
Lady Gaga as Harley Quinn: A psychiatrist who falls in love with Arthur.
Zazie Beetz as Sophie Dumond: A cynical single mother whom Arthur fantasized as his love interest, but in reality, they had only met once.
The 2019 film Joker was intended to be standalone with no sequels, although Warner Bros. intended for it to launch DC Black, a line of DC Comics-based films unrelated to the DC Extended Universe (DCEU) franchise with darker, more experimental material, similar to the DC Black Label comics publisher.
