The one off doco will be called, Harry Potter: A History of Magic will go behind the scenes of the movies, and of course, delve into the wizarding world that J.K. Rowling built.
We will see unseen manuscripts, drawings and drafts from her own personal collection, and what inspired her for some of the most famous story points and plot lines.
Famous fans will also do readings to recreate some of their favourite spells, potions and ~magical~ moments.
Oh, and of course it will follow IRL wand makers and Quidditch players.
Get your cauldron cakes and Butterbeer ready kids. This will be wild.
