Meticulously planned, to the extent where the animators all became qualified divers, Finding Nemo introduced an vast and immersive other world, beneath the sea. And to think the myriad reefs and sea-scapes are only a backdrop to the oddly human tale of a father who loses his son (metaphorically, thanks to his over-bearing paternal anxiety, and physically). The trailer is a thing of beauty, showing off not only the beautiful setting, but also introducing one of the film's big guns, in the shape of Dory early on. A wise move, considering how well her charisma comes across. If anyone had any doubt about Pixar's ability to tick off another impressive target from their list - the convincing reproduction of water using animation - the teaser material here is the perfect antidote. http://youtu.be/OEpC4w_djLA
