How to Train Your Dragon: The Hidden World

How to Train Your Dragon: The Hidden World


This is the third in the series of How to Train Your Dragon movies, based on the books by Cressida Crowell. Hiccup (voice of Jay Baruchel) is now the chief of the Viking tribe of Berk, where he has created a peaceful haven for dragons. He discovers, however, that an evil villain, Grimmel (F. Murray Abraham), is capturing dragons with the aim of killing them all. Along with several of his men and women, including Astrid (America Ferrera), Hiccup attacks the fortress where the dragons have been imprisoned to set them free.

Grimmel has a secret weapon, however, in the form of a beautiful white night fury called Light Fury, with which he plans to lure away Toothless, Hiccup's own night fury. Grimmel believes that if he captures the alpha dragon, all the other dragons will follow. Many battles ensue, and Hiccup decides that the only way for the dragons to survive is to find the mythical 'hidden world', which his father had told him about. Hiccup leads his tribe on the search for this mysterious place with mixed feelings. Toothless must decide whether to follow his heart or his loyal companion.
