Is Joaquin Phoenix coming back to reprise his award-winning role from 2019's Joker? We don't know. But, if you believe the recent reports, a follow-up is already confirmed, and filming is set to begin in 2023.

Last year, Joaquin Phoenix played coy when asked about rumors of a Joker sequel. Back then, the decorated actor did not confirm nor deny that a Joker 2 is in the works. However, this hasn't stopped reports of Joker 2 doing the rounds.

In particular, a recent rumor from Heroic Hollywood confirms that Todd Phillips will return to write and direct a sequel featuring Phoenix as Arthur Fleck, better known as the Joker.

According to the same source, the sequel will begin filming in 2023 albeit it declined to reveal more about the plot and other important details such as returning as well as new characters.

Over the past few years, fans, insiders, and leakers alike each have offered their takes on a potential Joker sequel. The prevailing theory these days is that Joker and Matt Reeves' The Batman are both set in the same cinematic universe. Meanwhile, others think that The Batman is a spiritual sequel to Joker, as both films are taking a character-driven approach to the titular characters. Of course, this are all speculation based on unconfirmed information.
