Michael Sporn has started posting the storyboard to Pinocchio, supplied to him by animation historian (and Oscar winning animator) John Canemaker. There is no question that Pinocchio is one of the most important animated features ever made, so the attention it's now getting from bloggers like Hans Perk, Sporn and myself is very welcome.
In a previous comments section, the spectre asked what the Pinocchio layout artists did. Comparing the board to the finished film is the best way to understand it. The boards do not contain the same level of design and detail in the backgrounds and the camera angles are only approximate. The layout artists are responsible for nailing down the camera angles, composing the shots and designing the backgrounds. My assumption is that the credited layout artist for a sequence was drawing as well as supervising the work of other artists.
