The Sea Beast is an epic Netflix adventure film which tells the story of Jacob Holland, a legendary sea monster hunter whose life is turned upside down when a young girl, Maisie Brumble, stows away on his ship and finds an unlikely friend in a terrifying sea monster.

This animated sea escapade is directed by Chris Williams, who has worked on the likes of Moana, Big Hero 6 and Bolt.

He told Variety (opens in new tab): “The Sea Beast is the kind of story I’ve always wanted to take on. It’s a tale of high adventure where our hero leaves the known world and ventures out into uncharted waters. As it turns out, I’m doing the same thing.”

Also according to Variety, The Sea Beast has also been inspired by the marvelous creatures on 16th and early 17th-century nautical maps.
