An animator is just as much an actor as someone who performs on screen. Animators have to know how all their own facial and body movements work to be able to create a believable character. Who is your favourite animator? Is it someone who is still alive and working today, or someone from the golden era? Do they work with a pencil or a computer?
My favourite animator is Chuck Jones. He animated characters such as Wylie E. Coyote and Tom & Jerry. I love the eye movement he gives them; that's usually a give away that he was the animator in a cartoon.
