Joker was such a smash that Joaquin Phoenix won an Oscar. For a comic book character!
So you knew Joker 2 was coming, but did you know it will be a musical? And did you further know Lady Gaga is in talks to play Harley Quinn opposite Joaquin Phoenix in Joker: Folie A Duex?
(Folie A Duex translates to an identical or similar mental disorder affecting two or more individuals, usually the members of a close family).
