How to Train Your Dragon is an upcoming American action fantasy film written, directed and co-produced by Dean DeBlois. It is a live-action adaptation and shot-for-shot remake of DreamWorks Animation's 2010 animated film, which itself is loosely based on the book series by Cressida Cowell. The film stars Mason Thames, Nico Parker, Nick Frost, Julian Dennison, Gabriel Howell, Bronwyn James, Harry Trevaldwyn, and Ruth Codd, with Gerard Butler reprising his role as Stoick the Vast from the animated films. It is DreamWorks Animation's first live action film production and the first live-action remake of any of their films.
