Arguably the finest of all of Pixar's aesthetic accomplishments, the world of
Ratatouille is a wonderful visual experience, complexly and intricately observed, injected with a tangible Parisian feel that forms the perfect backdrop to the story of Remy the culinary rat.

And here, without further gushing is the original trailer: http://youtu.be/xfiC_gdPTSk
