Joker 2 starring Idris Elba.
It starts off from the psych ward in the last movie. Joker’s change of appearance is not acknowledged by anyone
Midway through the movie Danny DeVito replaces Elba
Combine it with the storyline of copycat Jokers running around, and make it really unclear who is supposed to be the real Joker at any given time, then reveal that the entire movie has been from Bruce Wayne's POV as he hallucinates that every poor person in Gotham is the Joker because he was traumatized by seeing a talk show host get shot as a kid.
I did like Joker. But it was inevitable when it made a billion dollars that there would be a Joker 2. But we don't need a Joker 2. No one needs a Joker 2. Please.
If there is a God in heaven, I demand He kills everyone.
I think they're just saying that Joker, like Uncut Gems, 1000% does not need a sequel of any sort
