Fan Casting Doctor Finklestein in The Nightmare Before Christmas

Dr. Finkelstein is a frail-looking person with thin, spindly limbs and very small hands and feet but a disproportionately large head. He is confined to a black, electric wheelchair that seems to be rather old and difficult to operate. He dresses in a long white lab coat that buttons up on the right side, pants of the same color, black shoes, and black gloves that are a good deal wider than his arms. His skin is an unhealthy white color and he has small, beady black eyes, normally covered by his goggles, as well as thin black eyebrows. His mouth is beak-like in structure and he seems to be missing a few teeth.
