'Fantastic Beasts: The Secrets of Dumbledore' Final Trailer Prepares Audiences for a Wizarding War

To prepare you for Fantastic Beasts: The Secrets of Dumbledore, which is in U.S. theaters April 15, Warner Bros. has released one more trailer for the latest installment in the fantasy franchise.

Fantastic Beasts: The Secrets of Dumbledore, which already opened in the U.K. and thus far as a Metascore of 49, is set in the 1930s, following Aldus Dumbledore (Jude Law) as he builds an army for an impending war within the wizard factions. Dumbledore and his new recruit Newt Scamander (Eddie Redmayne) are on one side of that war, with Grindelwald (Mads Mikkelsen) on the other.

"The world as we know it is coming undone. Things that seem unimaginable today will seem inevitable tomorrow," Dumbledore says in the trailer, which you can watch below.

To learn more about that, he notes you have to listen to your past, but it will also require trust in him — "even when every instinct tells you not to." Each character is given a distinct role to play in preparing for the war, and yes, that comes with new wizard wands. But it will take more than strength in numbers to defeat Grindelwald, who promises to burn down the world.

It is almost time for these wizards to fulfill their destinies and transform the world.

The film also stars Ezra Miller, Dan Fogler, Alison Sudol, Callum Turner, Jessica Williams, Richard Coyle, and Katherine Waterston. It is written by Harry Potter author J.K. Rowling and Steve Kloves, and directed by David Yates. Executive producers include Neil Blair, Danny Cohen, Josh Berger, Courtenay Valenti, and Michael Sharp, while Rowling, David Heyman, Kloves, Lionel Wigram, and Tim Lewis produce.

It is the third series in that franchise but the 11th overall in the Wizarding World franchise that also includes Harry Potter. It is a followup to 2016's Fantastic Beasts and Where to Find Them, which received a 66 Metascore, and 2018's Fantastic Beasts: The Crimes of Grindelwald, which has a Metascore of 52.
