“Fantastic Beasts: The Crimes of Grindelwald” is essentially about a war between the light and dark. However, in a new video that has been released online, scriptwriter and author of the “Harry Potter” books JK Rowling explains how it is human nature to always consider the other side to be the dark side.

In a video posted on the YouTube channel of AT&T, Rowling noted that the name Grindelwald is mentioned in the very first “Harry Potter” book. The writer has been waiting to tell the back-story of this dark wizard for over ten years now, she said.

Rowling said that the phrasing of the story of the upcoming movie as a battle between light and dark is interesting because it is human nature to simplify everything and put people in two categories- either good or bad. However, everyone in the war always see themselves as the good guys, even though they are perceived as bad by the others.

The video also includes an interview with Jude Law (Albus Dumbledore). Law explained that his character is always three steps ahead of the others, and he has the ability to lead people into doing things that they don’t necessarily want to do. In this particular case, the professor will be leading Newt Scamander (Eddie Redmayne) into a fight against Grindelwald.

The upcoming film will be quite different from the previous one, Redmayne explained. The first film was more like an adventure, but the sequel feels like a thriller, according to the actor.

Rowling too teased that things are becoming much more “darker” and “complicated.” Redmayne teased that the stakes are going to “ratchet to something more and more extreme.”

“Fantastic Beasts: The Crimes of Grindelwald” is set to be released on Nov. 15 in Australia. The film has been directed by David Yates.
