Since it was announced last year that J.K. Rowling's Fantastic Beasts and Where to Find Them would be made into a total of five movies, fans have speculated about their plot.
And, to celebrate the beginning of filming on the next instalment of the franchise, Pottermore just released a whole load of new information about the upcoming movies.
So here's what we know so far...
1. The movies' timeline began in 1926 and will end in 1945.
2. Jude Law has been cast to play a young Dumbledore.
A few months ago, Pottermore revealed that Jude Law will appear in the upcoming Fantastic Beasts movies as Dumbledore in his younger days as Transfiguration teacher at Hogwarts. Director David Yates said the actor "will brilliantly capture all the unexpected facets of Albus Dumbledore as J.K. Rowling reveals this very different time in his life".
