Johnny Depp only starred in a handful of scenes in the Harry Potter spin-off franchise, Fantastic Beasts, but he was a large part of it. The actor played the series’ antagonist, Gellert Grindelwald, in The Crimes of Grindelwald. But, after his intense performance as the genocidal wizard, a British publication reported he was a “wife-beater” to his ex-wife Amber Heard, he was dragged off the series by Warner Bros. 

Last year, it was announced Mikkelsen was taking his place as the legendary sorcerer. Fans of both Fantastic Beasts and Depp were not convinced he would be able to take over the role convincingly, and the actor himself has opened up about what went on behind the scenes.
