Wall-E was a variant on the cute robot story that we have seen in films like Star Wars (1977) indeed the sound effects in Wall-E are conducted by Ben Burtt who won an Oscar as the man who created the bleeps and bonks that made up R2D2s dialogue and others like K9 in the Tom Baker Doctor Who (1963-89, 2005 ), Short Circuit (1986) and Short Circuit 2 (1988) where Wall-E bears a number of resemblances to the design of No. 5, as well as the previous animated likes of The Iron Giant (1999) and Robots (2005). Wedded to this is the robot romance story that we have seen in films such as Heartbeeps (1981), Electric Dreams (1984) and Making Mr Right (1987).
With its incredibly soulful and expressive eye lenses, Wall-E instantly becomes one of the most endearing of anthropomorphic robots imagine a mechanized combination of E.T. and Charlie Chaplins Little Tramp. There is something beautifully sad and melancholy about Wall-Es journey through the deserted ruins at the beginning of the film, compacting the junk, finding a new set of treads for himself then hanging them up in his container, bringing back a Twinkie for the cockroach to inhabit, then retracting his extremities and putting himself on the shelf for the night. The climactic scenes where he is battered out of shape and then brought back to life, only to appear to have had his memory wiped are heart-breaking.
I am happy to go out on a limb and call Wall-E Pixars finest film to date. A considerable part of the charm of Wall-E is the fact that more than half the film comes without any dialogue, just sound effects. The two robots do talk after a fashion but even then the ships computers dialogue has been created using the Macintalk text-to-speech program. As a result, almost the entire film is carried by the visuals and the sound effects, rather than speech. (Expectedly, Ben Burtt picked up another Oscar nomination for his work here). Indeed, in its emphasis on visual gags as opposed to dialogue, Wall-E is almost the modern equivalent of one of Buster Keaton or Charlie Chaplins silent comedies.
The film has an endless degree of visual invention. The visuals become especially charming during the romance between Wall-E and Eve his tentative attempts to reach out and take her hand, the doleful/comic scenes of him wondering what to do after she goes into stasis sitting on the pile of junk mournfully kicking his treads, holding an umbrella over her but getting jolted by a lightning bolt, trying to hold her hand as they sit watching the sunset only to get his claw trapped under her edges. There is a magical scene during the middle of the film with the two of them dancing around the outside of the ship in the void with Wall-E propelled by a fire extinguisher (even if the scene does require Wall-E to be making some unscientific curved turns in space). The slapstick scenes running around the ship may be drawn out slightly longer than needed but have an amazing degree of charm and plain good-natured humour. As always in a Pixar film, the show is frequently stolen by the supporting characters in particular, the cockroaches and a tiny cleaning steward bot that chases all over the Axiom cleaning up Wall-Es trail of grime. As with any Pixar film, the quality of the animation is exquisite the backgrounds of the junkyard future are stunning in their detail.
There is a modestly pro-environmentalist message underlying the film. What is also interesting about Wall-E is that contrary to almost every other film on machine-human relationships from 2001: A Space Odyssey (1968) through The Terminator and The Matrix series it does not create a black-and-white divide that says it is good to be human, bad to be machine and where the emotional climax of the story is the triumph of humanity over machine. Rather, humans have been atrophied by the convenience society to the point of being near-useless blobs and the robots become the unrecognised protectors of humanity and saviours of Planet Earth. However, this is perhaps more understandable a theme coming from Pixar a company that created their own triumph of the mechanised in being able to make computer animation into a medium that came to supplant human-hand drawn animation and made characters produced inside a machine environment into some of animations most warmly appealing.
There are a great many 2001: A Space Odyssey references and in-jokes throughout to the medbot with its single red eye just like HAL 9000 to the Also Sprach Zarathustra playing as the captain waddles out of his hover chair for the first time and it is interesting to make contrast between the two. Stanley Kubrick saw that humanity had become dehumanised by its tools and machines and all that the future held was technology triumphant; Wall-E proceeds in similar directions but sees the future where the machines have taken over as less threatening and in fact takes the side of the machines. Andrew Stanton sees the problem as not so much a case of machines overrunning the world but of humanity being trapped inside the convenience and consumerist society even the Earth has become uninhabitable after being overrun by the throwaway junk of human society. (Pixar are not above including themselves in such criticisms of the disposable consumer society there is one of the Pizza Planet trucks from Toy Story amid the junk, while Wall-E watches his films on an I-Pod, which is of course produced by Pixar CEO Steve Jobs Apple Computers). The answer however is a less bleak one than what Stanley Kubrick saw simply that of people being able to get up and walk again and allowing plants to flourish in soil.
Andrew Stanton subsequently went onto make the live-action adaptation of Edgar Rice Burroughs interplanetary swashbuckler John Carter (2012), which proved an expensive flop whereupon he returned to Pixar for Finding Dory (2016).
