Depp's ex-wife Amber Heard, who accused the actor of domestic abuse two years ago.
In a statement, she said: 'As described in the restraining order and divorce settlement, money played no role for me personally and never has, except to the extent that I could donate it to charity and, in doing so'. "However, around the time of filming his cameo in the first movie, stories had appeared in the press that deeply concerned me and everyone most closely involved in the franchise", Rowling said in the statement.
"When Johnny Depp was cast as Grindelwald, I thought he'd be wonderful in the role".
Warner Bros. said it takes seriously the "complexity" of the issues involved, which surfaced at the time the short marriage between Depp and Amber Heard was breaking up late past year.
"Based on our understanding of the circumstances, the filmmakers and I are not only comfortable sticking with our original casting, but genuinely happy to have Johnny playing a major character in the movies", Rowling concluded. Subsequently, Heard and Depp released a joint statement saying their relationship "was intensely passionate and at times volatile, but always bound by love". "Neither party has lied nor made false accusations for financial gain".
"Fantastic Beasts" director David Yates, left, said this of the accusations made against Johnny Depp: "It's a dead issue". For me personally, the inability to speak openly to fans about this issue has been hard, frustrating and at times painful.
But J.K. Rowling wrote the scripts, and the Harry Potter universe is her domain.
Fantastic Beasts: The Crimes of Grindelwald opens in theaters on November 16, 2018.
The author said she has found it "frustrating and at times painful" not addressing the issue but that two people's privacy had to be respected.
"I accept that there will be those who are not satisfied with our choice of actor in the title role", she conceded, "However, conscience isn't governable by committee".
'So if I understand correctly the actor who played Crabbe, a minor character, was sacked from Harry Potter for doing drugs. Within the fictional world outside it, we all have to do what we believe to be the right thing'.
Yates added: 'None of us involved in Fantastic Beasts would ever let our appreciation of talent obscure other, far more important considerations.
