Earlier this month, we found out there's a script for a Joker sequel with JOAQUIN PHOENIX called Joker: Folie a deux. Now we learn that Lady Gaga is in talks to play Harley Quinn? AND, the same sources say it's also going to be a musical.
It makes sense that Harley Quinn's character would be in it since the title Folie a deux references a medical term for an identical or similar mental disorder that affects two or more individuals, hence Harley Quinn.
We haven't heard anything official with the actors and no other details are known. What do you think of this idea of a musical?
