Literally everything about director Todd Phillips’ Joker origin movie sounds ridiculous, from casting a painfully serious actor like Joaquin Phoenix as the villainous clown to creating a Joker origin story that may or may not feature Batman at all, but Phoenix’s supporting cast might be the weirdest part of all. As we previously reported, Joker will also feature Robert De Niro, Zazie Beetz, and Frances Conroy, all of whom seem like they’re a little overqualified for what is essentially a spin-off of the big-time comic book movies (even if it will technically be unrelated to Suicide Squad and Justice League).
