Loved the first HTTYD, and hope the second one's just as good. Looks like it, as this new trailer sells the family drama of Hiccup's reunion with his long lost mother (Cate Blanchett, fresh off her Oscar win) over the action of all the flying dragons (we already know that stuff's going to be great). The first one was one of Dreamworks' best animated movies- with any luck the sequel could be one of this year's best as well. It's coming out Jun 13th and is the second in a planned trilogy, which is actually attempting to do something quite different for animated films, and that's age the characters as the movies progress. You can already see in this one that the teenagers from the first film are now young adults- and that's something they rarely (if ever?) do in animation, so it'll be interesting to see how that works out.
