Todd Phillips has been speaking on how 'open' he is to a Joker sequel, following the runaway box office success of his first foray into the world of comic books.

And with a return like that, it hardly seems likely that Warner Bros will be walking away.
Phillips told Deadline: “When a movie does $1 billion and cost $60 million to make, of course it comes up.
“But Joaquin and I haven’t really decided on it. We’re open. I mean, I’d love to work with him on anything, quite frankly. So who knows? But it would have to have a real thematic resonance the way this one did, ultimately being about childhood trauma and the lack of love, and the loss of empathy.

“All those things are really what made this movie work for us, so we’d have to have something that had an equal thematic resonance.”
That said, Phillips has also said in a separate interview with Indiewire that thus far 'there’s not a contract for us to even write a sequel, we’ve never approached Joaquin to be in a sequel'.
But Phoenix has gushed about how much he loved making the movie, which followed the disturbed stand-up comedian and party clown Arthur Fleck as he is pushed to the edge of sanity and into the abyss.
