The unexpected comic book movie blockbuster of 2019 was Todd Phillips’ Joker, starring Joaquin Phoenix in the title role of Batman’s #1 nemesis. The movie earned a billion dollars at the box office and won Phoenix an Academy Award for his role as Arthur Fleck. No one saw all that coming for the relatively smaller budget and very adult-skewing R-rated film. But when you make that much money, a sequel is inevitable.

Lady Gaga recently shared that her version of Harley Quinn will go by “Lee.” Gaga shares “My version of Harley Quinn is ‘Lee,'” Gaga said. “In a lot of ways, I think this is going to be a very different Lee for people, and I’m excited for them to see the story we wanted to tell.”

Here’s everything we know about the Joker sequel.


The official title for Todd Phillips’ sequel to his 2019 blockbuster hit is officially Joker: Folie à Deux. Which means, in French, “Joker: Shared Madness.”

Joker: Folie à Deux‘s Plot

Warner Bros.

Right now, we know little of the plot for the Joker follow-up. Other than the fact that it will feature the Joker and Harley Quinn together. Considering how loosely the first film played with DC Comics’ mythos, don’t expect this one to be any different. They explored the origin of the Joker/Harley relationship in the classic Batman: The Animated Series episode “Mad Love,” and then translated (more or less faithfully) in the first Suicide Squad movie. We expect something a little more out of the box this time for Joker and Harley.

For those concerned, Peter Safran and James Gunn have assured fans the movie will remain in the DC Universe, though it will carry an Elseworlds project tag. That means it will live on, but it won’t work into the main timeline of the DC Universe.
