Harry Potter fans are about to enter the world of Albus Dumbledore.
Rowling’s spin-off movie Fantastic Beasts: The Crimes of Grindelwald tells the story of the headmaster’s son.
The movie, the second in the Fantastic Beasts series of Potter prequels, opens in US cinemas on 18 November.
It will have its UK premiere the next day, 20 November, and also on the morning of 20 November.

Harry Potter fans might recall that on the final day of filming on the first film in 2015, Warner Bros streamed the Harry Potter and the Deathly Hallows – Part 2 trailer on its own YouTube channel.
At the time, Rowling said: “We’re just like fans, except we don’t get to see the finished product until it’s out on the big screen.”
Fantastic Beasts and Where to Find Them tells the story of American wizard Newt Scamander, played by Eddie Redmayne.
Rowling has said the series will tie into events in the Potter saga and he will have grown up in the 70s, which is close to how the central character Harry did.
The second film is directed by David Yates, who directed the final four Harry Potter films from 2010 onwards.
The Crimes of Grindelwald, starring Johnny Depp as Grindelwald, Katherine Waterston as Tina Goldstein and Dan Fogler as Jacob Kowalski, is based on a screenplay Rowling wrote with JK Rowling, Colin Farrell and Jude Law.

While Fantastic Beasts the film was a critical success, merchandise sales were disappointing – particularly after last year’s return of the brand to the UK movie theatre.
In March the latest Potter phone charger was withdrawn from stores and only sold a limited number of copies.
But it will be available in Comic Relief’s Snowbombing – but not at premiere.
The next Harry Potter book, Harry Potter and the Cursed Child, was released in July 2016 and established a Wizarding World of London Stage which has just completed its second run.
Is this a sign we are seeing a Harry Potter theme park soon?
