From the news story:
Acclaimed actor Jude Law will play Albus Dumbledore in the sequel to Fantastic Beasts.
The second film in the Fantastic Beasts series will show Dumbledore decades before he became Headmaster at Hogwarts School of Witchcraft and Wizardry.
At this point in the story he is the wizarding school’s Transfiguration professor and a contemporary of Gellert Grindelwald – the Dark wizard we met in Fantastic Beasts and Where to Find Them, played by Johnny Depp.
The stage is set for Dumbledore to make his presence known and returning director David Yates said, ‘Jude Law is a phenomenally talented actor whose work I’ve long admired and I’m looking forward to finally having the opportunity to work with him. I know he will brilliantly capture all the unexpected facets of Albus Dumbledore as J.K. Rowling reveals this very different time in his life.’
