How to Train Your Dragon: The Hidden World

How to Train Your Dragon: The Hidden World is a 2019 American animated fantasy film written and directed by Dean DeBlois, based on the book series by Cressida Cowell. Produced by DreamWorks Animation, it is the sequel to How to Train Your Dragon 2 (2014) and the final installment of the How to Train Your Dragon trilogy. The film features Jay Baruchel, America Ferrera, Cate Blanchett, Craig Ferguson, Gerard Butler, Jonah Hill, Christopher Mintz-Plasse, Kristen Wiig, and Kit Harington reprising their roles from the first two films, with F. Murray Abraham joining the cast. The film follows 21-year-old Hiccup seeking a dragon utopia known as the "Hidden World" while coming to terms with Toothless's new bond with a female Fury, as they deal with the threat of Grimmel the Grisly, a ruthless dragon hunter.

Discussions regarding a third How to Train Your Dragon film began in December 2010, with DeBlois later stating that the second film was being intentionally designed as the second act of a trilogy. The animation challenges of the production required DreamWorks Animation to update and invent new software to handle complex tasks, such as lighting the Light Fury dragon.

How to Train Your Dragon: The Hidden World was released theatrically in Australia on January 3, 2019, and in the United States on February 22, 2019, by Universal Pictures. Like its predecessors, it received positive reviews, with critics considering it a satisfying conclusion to the trilogy, with praise for its animation, voice acting, score, and emotional weight. The film grossed $540 million, and received several accolades, including five Annie Awards nominations, a Golden Globe nomination, and a nomination for Best Animated Feature at the 92nd Academy Awards.
