"The whole principle of casting the movie was go for the best actor; go for the most inspired, interesting, right fit for that character. As we started to approach Grindelwald, we thought: 'Who's going to take this in an interesting direction?'

"Johnny Depp is a real artist and he's created several characters who have really resonated in our popular culture. He's a really brilliant, brilliant actor and we were excited about seeing what he would do with this kind of character. He's fearless, he's imaginative, he's ambitious. We thought he'd do something fun and special. So we went for him purely on that selfish basis, we don't care if he's famous or not famous, we just know he's interesting."
He also said Depp was cast before his divorce from Amber Heard
