It's looking likely that a Joker 2 movie is in the works from Todd Phillips and Joaquin Phoenix, but there are many other DC Comics villains who deserve the spotlight instead.
THR reported in 2019 that Phillips was in talks to return as director for a follow-up and that he would the script with Scott Silver, who worked on the first movie s screenplay.
However, Phillips played down the suggestion, saying of the story: I have to be honest, it came out of nowhere. It referred to a meeting that was never had. I thought it was anticipatory at best.
If it is indeed going ahead, the biggest question mark hanging over the sequel right now is whether or not Joaquin Phoenix will reprise his character Arthur Fleck, who closed out the 2019 psychological thriller running rampant in Arkham Asylum.
