In news that surprises nobody, Jesse Eisenberg has been removed from the forthcoming DC Universe Avengers, Justice League. His portrayal of Lex Luthor was widely hated by pretty much everyone and panned by every single critic. That’s not opinion, it’s science. As has been noted, Justice League has a lot of plot to develop and a lot of action to unfold in limited time, so every scene is precious. It’s possible it just got too crowded to focus on an already established character.
Or they’ve come to their senses and decided never to let JE play LL again.
