Cars Anatomy by Jake Parker
I don't know about you, but I have definitely wondered how exactly the cars in the Disney movie Cars were supposed to be alive, at least, in the weird half real, half not real world that is Cars. These rad rendering were done by illustrator Jake Parker and he does a much better job of articulating this bizarre thought:
I had that exact same thought when I first saw Cars, glad I'm not the only one! I don't recall them ever needing to eat in the first film, but this at least clarifies some of the anatomical mechanics that could be involved. Now I guess I should watch Cars 2, no doubt with this in mind.
