J. K. Rowling is writing a new movie set in the wizarding world.

It won’t feature the character Harry Potter, but it is inspired by one of the boy wizard’s textbooks: Fantastic Beasts & Where to Find Them, “written” by fictional author Newton Scamander.

Warner Brothers film studios told Rowling they wanted to make a movie based on the fictional textbook, used by Potter and his friend, Ron Weasley.

The new movie will feature the adventures of a 21-year-old Newton Scamander.

Scamander is an expert in Magizoology, the study of magical creatures.
