Russel Hall animated most key scenes with Jessica. His take on the character is unique as you can see in these two spectacular rough drawings. Her sensual qualities could have been portrayed in a cliche, overly cartoony way. But Russel developed a brand new animation style, based on realism and American pin up. He was the perfect animator for this character.
If you know Russel's work, you find that he was equally capable of handling broad exaggerated designs as well.
