The first Pixar film to be nominated for 6 Academy Awards. This ties it with the only other animated film to garner this many nominations: Beauty and the Beast (1991).
WALL·E stands for: Waste Allocation Load Lifter: Earth Class. EVE stands for: Extra-terrestrial Vegetation Evaluator.
To explore the possibilities of pure visual storytelling, Andrew Stanton and the Pixar team watched every single Charles Chaplin and Buster Keaton movie, both short films and features, every day during lunch for about 18 months.
(at around 33 mins) The last piece of debris that clears away from WALL·E as he leaves Earth's atmosphere is the Russian satellite Sputnik I, which in 1957 was the first man-made object to be placed in Earth orbit.
