This has been building since before Toby Emmerich exited and Michael De Luca and Pam Abdy took the reins at Warner Bros. Joaquin Phoenix hasn’t quite signed a deal to reprise his role as the disturbed murderous anarchist Arthur Fleck in a sequel to the billion dollar grossing Joker,. but the film is a go. Director Todd Phillips revealed on Instagram that there’s a Joker sequel script he just wrote with Scott Silver and that Joaquin Phoenix, who won an Oscar for playing the title role, is reading it. That isn’t quite true; Phoenix read it awhile ago, and it has come down to making a rich deal for him to star in the genre-jumping sequel.
