Disney is currently in the middle of a run of live-action movies, but it isn't their first foray away from animation. They've done it before, and one of the products of that era was 'Watcher in the Woods,' which may as well be a horror movie.
During a seance, we see a terrified, blindfolded girl who goes missing as a chapel is struck by lightning and then burns down in the middle of a storm. Hardly the stuff childhood dreams are made of.
