We already have the first trailer for the next animated release from Blu Sky Studios, the creators of the "Ice Age" saga, who had a bump with "Robots" and took flight with "Horton".
The new film in question is titled "River" and it will be set in Brazil, specifically in Rio de Janeiro, in the trailer we can see the publicity that they do to the city, with the story of the parrot that is afraid of flying.
The film "Rio" will be released on April 8, 2011.
