FILM 1728: HOW TO TRAIN YOUR DRAGON 2
TRIVIA: The first Dreamworks Animation film to win a Golden Globe award for Best Animated Film.
When Astrid says to Eret, "Don't you know anything." That is a reference to when Ygritte says to Jon Snow, "You know nothing, Jon Snow." Kit Harrington plays both Eret and Jon Snow from Game of Thrones.
The drawings on the wall in the Dragon stables in Berk were actual drawings done by the children of the crew who worked on the film.
Was the frontrunner for the Academy Award for Best Animated Feature, but lost to Big Hero 6 (2014).
