This short clip of the iconic Calvin and Hobbes' dance in the woods by Canadian animator and compositor Adam Brown makes me want an animated cartoon so badly. One that is silent because, really, no actor would be able to get their voices right.
The idea that no actor could get the voices right is something Bill Waterson has put into the public consciousness. And I don't think he's correct. With the right time and attention you could do a series of shorts that would perfectly represent the strip. He doesn't want that and I respect it. But it's not impossible. it would just take a lot of work and attention from him whatever studio handles the production.
