How to Train Your Dragon (also released by the name How to Train Your Dragon 3D) is a 2010 computer-animated fantasy film by DreamWorks Animation very loosely based on the 2003 book of the same name. The film stars the voices of Jay Baruchel, Gerard Butler, Craig Ferguson, America Ferrera, Jonah Hill, T.J. Miller, Kristen Wiig, and Christopher Mintz-Plasse.
The story takes place in a mythical Viking world where a young Viking teenager named Hiccup aspires to follow his tribe's tradition of becoming a dragon slayer. After finally capturing his first dragon, and with his chance at finally gaining the tribe's acceptance, he finds that he no longer has the desire to kill it and instead befriends it. The film was released March 26, 2010, to universally positive reviews. The film grossed half a billion dollars and became DreamWorks Animation's fifth most successful film in the United States and Canada (behind the Shrek film series).
