Coraline Movie

Inside most animated movie studios, the workplace background noise is little more than gentle mouse clicks and the dull drone of computers. The sounds within Laika, the maker of the new stop-motion animated film "Coraline," are often distinctly different: the buzz of electric drills, the whir from sewing machines and the occasional wallop of a hammer. Animation has grown into not only a billion-dollar business but also a high-tech hotbed of visual effects.
