‘Clayface’ Officially Sets Up Another Iconic Batman Villain in the DC Universe

*Clayface* includes several references to the Joker, but the character does not appear in the film. The details point to a nod to Batman’s wider world rather than confirmation that the Joker is already part of the DC Universe’s Gotham.

Set photos showed “The Jokers” graffiti and a “Join the Joker” flyer, though neither is clearly featured. More definite references include a giant clown sign at Amusement Mile, a TV mention of a film called *One Bad Day*, and a scene in which Matt Hagen’s face is cut into a grin reminiscent of Heath Ledger’s Joker.
