Legend of the Guardians trailer

Oh my god have you seen this!?! The animation is amazing! The detail and textures in this trailer are mind boggling! It would have taken them ages just to get the feathers to ruffle the right way! It looks like such a beautiful film as well, simply by the atmospheric effects with lighting and layout.
Its truly extraordinary how animations have progressed over the last 10 years (saying that makes me feel old).
