When news first broke that the guy that made Road Trip was directing an 80s set standalone Joker movie, expectations weren't high. The casting of Joaquin Phoenix as the titular character instantly made the film a curiosity, but nobody could have predicted Joker would break every possible record for an R-rated movie. 

At the time of writing, Joker is sitting on a global haul of $998 million, which means by the time you're reading this The Clown Prince of Crime would have crossed the $1 billion line. Surpassing both Deadpool and its sequel, Joker is the first-ever R-rated movie to make $1 billion. In addition to breaking records, Joker gives Warner Bros their first $1 billion blockbuster since Aquaman, and it's the second non-Disney movie to reach that sum at the global box office this year. Technically, Spider-Man: Far From Home shouldn't count as Marvel Studios had a hand in making it, but I won't be that pedantic.

Naturally, the unprecedented success has led to talk of a sequel, both Philips and Phoenix have discussed the possibility, but neither has confirmed a sequel is happening. Phoenix previously revealed that he'd had discussions with Philips about what the future could hold 

“You know, I wouldn’t have thought about this as my dream role. But now, honestly, I can’t stop thinking about it. I talked to Todd a lot about what else we might be able to do, in general, just to work together, but also specifically, if there’s something else we can do with Joker that might be interesting. So, it ended up being a dream role. It’s nothing that I really wanted to do prior to working on this movie.

I don’t know that there is [more to do]. Me and Todd would still be shooting now if we could, right? Because it seemed endless, the possibilities of where we can go with the character.”

Joker was designed to be a one and done film, away from the rest of the DC characters, and while I was a big fan of Joker, part of me hopes we don't see Arthur again. I mean I kind of want to see where it could go, or how it could influence Matt Reeves' The Batman, but there is something special about Joker being a singular experience.
