Johnny Depp fans have been campaigning to get Warner Bros. to rehire him as Gellert Grindelwald ever since he was removed from the Fantastic Beasts franchise last fall. The studio doesn't look like it's going to budge on that decision, though, with Mads Mikkelsen instead taking over the role. What's more, it's possible WB could end up casting someone in the Wizarding World that would make Depp loyalists pretty mad: the actor's ex-wife, Amber Heard.
