“If you listen carefully enough, the past whispers to you,” Law says before introducing the protagonists, which he describes as “a magizoologist, his indispensable assistant, a wizard descended from a very old family, a school teacher and a muggle.”

Mikkelsen is later seen in character announcing: “Our war with the muggles begins today.”

Depp stepped down from the role of Grindelwald following a legal battle with his ex-wife Amber Heard.

Mikkelsen, whose credits include Bond villain Le Chiffre and Dr Hannibal Lecter in the television series Hannibal, was later announced as his replacement.

Fantastic Beasts: The Secrets of Dumbledore is set to come out in cinemas globally on April 15, 2022.
