Fantastic Beasts franchise grows to 5 films

J.K. Rowling's Fantastic Beasts and Where to Find Themisn't going to be a movietrilogy, it's going to be a pentalogy.

At a fan event for the upcoming film in London on Thursday, the author revealed that the budding franchise will now stretch to five films.

The first, starring Eddie Redmayne, opens November 18.

• New edition of Hogwarts text Fantastic Beasts and Where to Find Them coming

• "Harry Potter is done now," confirms J.K. Rowling

The announcement, which Warner Bros. confirmed, immediately fueled conjecture that the Harry Potterprequel, set decades before Potter's birth, could lead right up to the young wizard.

The second Fantastic Beastsis already in pre-production, and due in theatres November 2018.
