Wall-E is an animated movie produced by Pixar Animation Studios and released by Walt Disney Pictures in 2008. The main character is the robot WALL-E (Waste Allocation Load Lifter: Earth-Class).

WALL-E didn’t talk so the filmmakers couldn’t rely on dialogue to convey emotion and transmit a story. That is why the film's story crew and animation crew watched a Keaton and a Charlie Chaplin film every day for almost a year to study how to present a story just by facial expressions.
