Animating for Commercials

It was not a field either Walt or Roy were happy to be in. Their reasoning was sound. We didn't own the characters we produced for other companies; there was absolutely no residual value. Worse, we were at the whim of the client; at each stage of production we had to twiddle our thumbs and await approval before we could venture on to the next step
- Harry Tytle (Disney producer)
