Frank examines storyboard sketches of a sequence from Robin Hood. He would later animate those very scenes. Not very thrilled with the way the film's story was coming together, Frank still did the best he could with the material given to him.
Following are just a few examples of animated moments in Frank's long career. To my eye there are zero formulas to detect in his work. Every one of his characters moves and acts in a unique way.
That way of working takes not only great analysis but a ton of passion.
