There are lots of people that do not get when I say that "Wall.e" is one of my favorite Pixar and animated filmes ever made. It is because I pronounce it "Wally" just like in the movie.
Well, some people watched it 5 or 6 times with their kids and still call it "wow E". Of course, the Pixar dudes thought of this pun with the term WALL.E, and while Wally gets older and for consequence, capable of having emotions, WALL.E turns out into Wally, the robot with human emotions. Wall.e is actually an acronym for Waste Allocation Load Lifter Earth-Class.
