The Reporter says its sources claim that “Warners has yet to close a deal with the actor, with the two sides deep into it”, but it is inconceivable the project will move ahead without his participation. In the same social media post Phillips also revealed a photograph of Phoenix reading the script, although reports say that Phoenix has not yet committed to the project. The Reporter also states that Joker 2 will be “a musical”, though offers no further details. Director and co-writer Todd Phillips posted a script cover page on social media on Wednesday suggesting the film’s subtitle is “Folie à Deux”, a reference to a psychiatric syndrome in which a delusional state is shared by two people, which could well refer to Quinn’s place in the film’s narrative.
No details of the film’s plot have been revealed, but the Reporter says that Joker 2’s Quinn will “exist in a different DC universe than … Robbie’s Harley Quinn” – presumably reflecting the first Joker’s distant relationship with previous iterations of the character.
