i animated the scene with zigzag holding the cobbler's hand . its nice to know the next gen of animators still rate dick williams and that film . it nearly killed me !!!!there never was a real finished DW version of the film - the last stage at which dick was involved was a two thirds animated film and full colour storyboards all drawn in marker pens by dick himself . i should know cos i was high for weeks !!!
So I'd guess that's the extent of what was completed under Williams' supervision - 2/3 of the film animated with the rest done in color storyboards by Williams.
