Then all hell breaks loose.
Whats notable about the trailer is that it teases a completely different power dynamic between Joker and Harley.
The trailer even ends with Harley saying she wants to see therealArthur, the man whodidsomething with his life.
Red lipstick on glass covers Arthurs face as he gives the audience one last smile.
Its only after he meets Harley in the trailer that he starts feeling like his old self.
To which Arthur replies, Im not alone anymore.
Joker: Folie a Deux opens in theaters on Oct. 4.
