Mikkelsen said earlier in the year that he “would have loved to have talked to” Johnny Depp about replacing him in Fantastic Beasts.

Speaking to The Times , Mikkelsen said: “I mean, obviously, they were going to do the film, and obviously he was not involved any more.

“But I didn’t have a dog in that fight. And I don’t know what happened [in his private life], and I don’t know if it was fair, him losing the job, but I just knew that the show was going on, and I would have loved to have talked to him about it if I had the chance, but I just don’t know him in that sense.

“But they called me and they were obviously in a hurry, and I loved the script and so said yes. And I know it was controversial for many people, but that’s just the way it plays out once in a while.”

The original cast of Harry Potter will reunite for a HBO special to celebrate the 20th anniversary of the first film, Harry Potter And The Philosopher’s Stone.

Daniel Radcliffe (Harry), Rupert Grint (Ron Weasley) and Emma Watson (Hermione Granger), alongside director Chris Columbus and other cast members over the franchise, will feature in the special titled Harry Potter 20th Anniversary: Return To Hogwarts.

The special will premiere January 1, 2022 on HBO Max in the US, with it expected to release on other platforms around the world.

Meanwhile, rapper Jack Harlow has said that the Harry Potter books are responsible for bringing out a competitive side in his personality that has boded well for his career.
