About How to Train Your Dragon (2025)
How to Train Your Dragon live-action film is directed by Dean DeBlois, who also directed the animated trilogy. This adaptation aims to bring the magical world of Berk to life with cutting-edge visual effects and real locations, while maintaining the heart and spirit of the original animated films.
The casting of Mason Thames (known for The Black Phone) as Hiccup and the return of Gerard Butler as Stoick creates a bridge between the animated and live-action versions. The film promises to deliver spectacular dragon sequences using state-of-the-art CGI technology.
About How to Train Your Dragon (2025)
How to Train Your Dragon (2025) is the live-action adaptation of the animated film series, returning to the story of Hiccup, the young Viking who befriends a Night Fury called Toothless and changes how his village relates to the dragons it has long fought.
Adaptation approach
The film keeps the bones of the original animated story while reworking the look of the world for live action. Practical effects on the village set, on-location photography, and modern dragon visual effects combine to recreate Berk and its inhabitants in a more textured, physical register without losing the energy of the source material.
Casting
Mason Thames plays Hiccup, with Nico Parker as Astrid, Gerard Butler reprising the role of Stoick the Vast from the animated films, and Nick Frost as Gobber. The supporting cast includes the young actors playing the other Viking teenagers training to fight dragons under Gobber's instruction.
Production
The film is produced and distributed by Universal Pictures with Dean DeBlois — director of the original animated trilogy — returning in a creative leadership role. That continuity is part of why the live-action film moves and sounds like a successor to the animated series rather than an unrelated reboot.
Where to watch

How to read this cast page
Cast lists work best as a quick reference rather than a transcript of the credits. The principal cast section above lists the actors most viewers will recognise from marketing and from the first episode or first act. The character each actor plays is shown alongside the name, with short relationship cues where they help.
Recurring versus principal cast
Television in particular distinguishes between “series regulars,” who appear in most episodes, and “recurring” or “guest” performers who appear only in some. Recurring cast can shift between seasons: someone introduced as a guest can be promoted to a regular role if the writers decide the character should stay. When that has happened on this title, we update the cast list rather than leave outdated billing in place.
Why character descriptions stay short
We keep character notes brief and free of spoilers. Late-season twists, deaths, and identity reveals are part of why audiences watch a show or a film, and a cast page that gives them away in the first paragraph is harder to use casually. If something is essential to introducing a character — a job, a family relationship, a faction — we include it; otherwise we leave it out.
Spelling and credits
Names are written here the way the production credits them. Where actors are credited differently in different markets, we use the credit listed in the production's official press notes. Stage names, mononyms, and special characters are preserved.
Suggesting changes
If you spot a name we have wrong, a character description that has gone out of date after a new season, or a credit that is missing, the contact page explains how to reach us. We update individual cast pages rather than rewriting the site, so corrections we receive turn into changes on this page directly.
