Everything to Know About the Upcoming ‘Joker’ Sequel, ‘Folie a Deux’: Cast, Release Date and More

Joaquin Phoenix’s Joker will make his big screen return alongside Lady Gaga.

Not long after Joker director Todd Phillips confirmed he would be writing and directing a sequel, Gaga confirmed her casting by sharing a video of her and Phoenix’s silhouettes dancing via Instagram. “Joker: Folie à Deux,” she captioned the August 2022 post. “10.04.24.”

Gaga is set to star as Harley Quinn, who is often depicted as being in an on-and-off, abusive relationship with the Joker in the comic books. The film’s title, Folie à Deux — a French term that refers to a “delusion or mental illness” shared by two people in close association — could be a nod to the difficult relationship between the characters.

Phoenix won Best Actor at the 2020 Oscars for his role as the Joker (real name Arthur Fleck). “I’ve been a scoundrel in my life,” he said in his acceptance speech. “I’ve been selfish, I’ve been cruel at times, I’ve been hard to work. I’ve been grateful [because] so many of you in this room have given me a second chance. … We help each other to grow, we educate each other, we guide each other to redemption. That is the best of humanity.”
