WALL-E is Pixar’s longest-running and arguably most successful experiment in using new storytelling that is radically simple. During the first twenty minutes of the cartoon, the viewer sees only an abandoned, in a sense devastated, but full of garbage Earth. There are no conversations on the screen, only background noise that echoes over long distances and is created by recording any advertising signs and other things. It appears to the viewer as if a silent movie, which was popular at the time of just the beginning of the development of any technology. Time on Earth has not just stopped; it is receded: WALL-E has a favorite 1960s movie cassette that’s the only reminder of humans.
In the reality of WALL-E, there are no dialogues on Earth because there is no one else to talk to. Oddly enough, there is no dialogue when humans eventually show up later in the film. The robots on the spaceship seem to be more intelligent than the people who created them. They make sounds and show their emotions on screens or through posture. That is, they entirely use non-verbal communication, although some even speak.
WALL-E has a lover with whom he dreams of repeating a scene from a movie he’s seen probably hundreds of times. WALL-E and Eve use only three words in their speech, each other’s names and ‘no.’ However, the intonation with which the heroes pronounce these words conveys their emotions, and when Eve feels happiness, she even laughs. In this cartoon, the robots have more feelings and humanity than the people represented there. Although there are no long, meaningful dialogues in the film, the creators used various non-verbal communication methods, background noise, and music to fill WALL-E with life and convey meaning and emotional development in the story.
