He told Indiewire that no deal has been made for a sequel of this gritty DC villain movie. He said: 

While Joaquin and I have talked about it, and while touring the world with Warner Bros executives — going to Toronto, and Venice, and other places — of course, we’re sitting at dinner and they’re saying, ‘So, have you thought about…?’. But, talking about contracts, there’s not a contract for us to even write a sequel, we’ve never approached Joaquin to be in a sequel.

All these 'sequel' speculations started when The Hollywood Reporter reported that Warner Bros. was moving forward with a Joker sequel and director Todd Phillips had a meeting with studio chairman Toby Emmerich on October 7 to ask for the "rights to develop a portfolio of DC characters’ origin stories."

Joker is the first R-Rated movie that crossed the $1 billion mark. Talking about this, Todd explained: 

“Well, a movie doesn’t make a billion dollars and they don’t talk about a sequel. Joaquin and I have publicly said we’ve been talking about a sequel since week two of shooting because it’s a fun thing to talk about. But the [THR] article was referring to other things than that that were just frankly untrue. I don’t know how it gets started, if it’s some assistant trying to gain street cred with a writer.

Honestly, Joker was an excellent movie and we don't really need a sequel to spoil the legacy. What are your thoughts on this?
