Harry Potter fans gathered in London yesterday (13 October) to watch a special screening of the first 10 minutes of Warner Bros' upcoming Fantastic Beasts And Where To Find Them. Star Eddie Redmayne and writer JK Rowling were also there, to take part in a Q&A, where they revealed that the film would be the first of five movies. And it's safe to say, fans were excited.

Despite being out next month, details of the movie's plot are being kept under wraps and there's no way of knowing what's in store for the further four movies after it. However, during the event, Rowling did reveal that later instalments will feature a young Albus Dumbledore and his former friend, Gellert Grindelwald.

While it has never been officially stated on screen (or in the books), fans have known for quite some time that Hogwarts headmaster Dumbledore is gay; a fact revealed by Rowling in 2007 when last book Harry Potter And The Deathly Hallows was first published.

In interviews around that time, the author also added that the professor had romantic feelings for Grindelwald when he was much younger but was "horribly, terribly let down" when was consumed by his love for the Dark Arts and killed Dumbledore's sister Ariana when duelling.

Dumbledore later overcame Grindelwald and become the owner of the Elder Wand – one item of the fabled Deathly Hallows – was convicted and imprisoned, where he spent the rest of his life until he was later murdered by Voldemort. But even if fans know how the story ends, examining the pair's complex early relationship will no doubt be interesting.

Set around 70 years before the events of the Potter saga in the 1920s, JK Rowling has insisted that the film will be in no way a prequel to the hugely popular franchise. Fantastic Beasts is based on a Hogwarts textbook, fictionally written by author-turned-magizoologist Newt Scamander as he travels all around the world to recover a number of creatures he's... well... misplaced, so to speak.

Directed by Potter veteran David Yates and also starring Carmen Ejogo, Ezra Miller, Katherine Waterston, Jon Voight and Colin Farrell, Fantastic Beasts And Where To Find Them is scheduled to reach UK and US cinemas on 18 November 2016.
