Now that director Todd Philips has revealed the script for Joker 2, fans are concerned about the toll that Joaquin Phoenix's extreme method acting could have on his body.
Phoenix has long been an actor celebrated for his intensity and willingness to embrace challenging roles and those traits served as the perfect recipe for the success he would achieve when he took on the daunting role of the Joker.
But while the actor often seemed to have his mind on other matters when he accepted accolades for that performance, his turn as the Joker is already considered legendary enough to possibly eclipse Heath Ledger's award-winning take on the character.
Much like the late Australian actor, however, Phoenix found that work of bringing the Joker to life was both physically and mentally demanding. And with that first consideration in mind, fans are now worried that doing it all again may not be worth it for him in the long run.
