Epic - the new movie from Blue Sky Studios looks... Epic (you knew that was coming right?).
I will happily admit I am not a fan of the Ice Age movies, but I quite enjoyed Rio - and Epic looks like the type of film that's right up my street. Like a tiny, slightly more cartoony, version of Avatar.
It looks like Blue Sky Studios have learnt a lot from Rio and carried over some of the visual stylings - in particular the things they learnt about birds and vegetation giving this trailer a really lush green look. There doesn't seem to be an official website about the film yet so you can check out the Epic page on IMDB for more info.
