Nu har Joker været i biograferne i noget tid, og ikke bare har den klaret sig ganske godt blandt anmeldere, den har formået at blive den bedst indtjenende film med en R-Rating nogensinde, efter at have slået Deadpool. Netop derfor er det kun naturligt at udvikle en efterfølger, men instruktør Todd Phillips har tidligere udtrykt skepsis omkring sådan en idé.
Nu virker det dog som om, at Phillips og skuespiller Joaquin Phoenix i det mindste snakker om hvordan de ville kunne gøre det. I et interview med The Envelope snakker de to om deres proces, og her siger de at de ikke længere udelukker det.
"Long before the release or before we had any idea if it would be successful, we talked about sequels. In the second or third week of shooting, I was like, 'Todd, can you start working on a sequel? There's way too much to explore.' It was kind of in jest — but not really," siger Phoenix.
Han slår dog også fast, at han ikke skrev under på kontrakten for at kunne lave flere film.
"I guess the fear was that you'd get locked into doing something repeatedly that you don't really care about, that doesn't motivate you or excite you. Part of the whole attraction to me [of Joker] was there was no expectation. I didn't sign a deal to do [more movies]. It was a one-off."
Dog siger Phillips, at de har snakket om at lave en efterfølger. Om hvorvidt dette bliver til noget vides ikke.
"We've only talked about the fact that if we ever did one -- and I'm not saying we are because right now we're not -- it couldn't just be this wild and crazy movie about the 'Clown Prince of Crime.' That just doesn't interest us. It would have to have some thematic resonance in a similar way that this does."
