Synopsis: In 1914, on the eve of war, a fugitive prince and a girl in disguise meet aboard a bioengineered airship, the HMS Leviathan, and change the course of history.

Based on the Leviathan trilogy written by Scott Westerfeld, illustrated by Keith Thompson.
Directed by Christophe Ferreira.
Music by Nobuko Toda & Kazuma Jinnouchi.
Original Songs by Joe Hisaishi.

Here’s how Westerfeld describes the Leviathan books:

“Prince Aleksander, would-be heir to the Austro-Hungarian throne, is on the run. His own people have turned on him. His title is worthless. All he has is a battletorn war machine and a loyal crew of men.

“Deryn Sharp is a commoner, disguised as a boy in the British Air Service. She’s a brilliant airman. But her secret is in constant danger of being discovered.

With World War I brewing, Alek and Deryn’s paths cross in the most unexpected ways, taking them on a fantastical, around-the-world adventure that will change both their lives forever.”
