Which film series did J.K. Rowling write about the magizoologist Newt Scamander?

J.K. Rowling wrote the screenplay series Fantastic Beasts about magizoologist Newt Scamander.

The film series begins with Fantastic Beasts and Where to Find Them, released in 2016. Eddie Redmayne plays Newt Scamander, a British wizard who studies magical creatures and becomes involved in conflicts within the wizarding world. The story is set decades before Harry Potter’s school years.

Rowling wrote the screenplays for three released films: Fantastic Beasts and Where to Find Them, The Crimes of Grindelwald, and The Secrets of Dumbledore. The films expand the Wizarding World beyond Britain, with major settings including New York and Paris.

The title comes from a Hogwarts textbook attributed to Newt Scamander, which first appeared as a companion book connected with the Harry Potter series. The film is therefore not another Harry Potter installment, even though the worlds and history overlap.
