I forgot how long Marc Davis worked on story for Bambi. He told me once, I think it was about five years. Marc skipped Pinocchio and Fantasia in order to focus on the challenge to develop sequences with realistic but expressive animal characters for Bambi.
In this particular sketch it's Thumper who just kills me. What an appealing, gorgeous, all around wonderful caricature of a rabbit.
I this photo, years later, Marc is pretending to work on Lady And the Tramp.
As a matter of fact, he skipped this film as well, so he could do designs for the next Disney film Sleeping Beauty. Marc created endless characters for crowd scenes, but as you all know, focused on Aurora and Maleficent.
