The amassed Wall-E bits and pieces from around the web amount to this: The film is (very nearly) silent with little dialogue - perhaps none at all. It's a love story about Robots in love. The two robots in love - and indeed, most robots we meet - have very different purposes, and therefore designs. WALL is an acronym, E is his series number - so get your think caps on... what does WALL stand for?
This film is considered by 'insiders at Pixar' to be ambitious, very funny and incredibly well conceived. The left hand side of the image above is the current logo, but it may be changed closer to the release date, next summer - as posted by Jim Hill Media. The right hand side, you've seen before.
