Mickey Mouse cast a magic spell over moviegoers with his entrancing role in "Fantasia" and rode a new wave of popularity. In this returning classic segment, the versatile mouse star finds himself in over his head when he puts on a different hat and tries to work a little magic of his own. Naturally he lands in deep water. "The Sorcerer's Apprentice" was the genesis for "Fantasia" back in 1937 and served as the springboard for Walt Disney's "Concert Feature."
