The 5,000 Fingers of Dr. T

Written by the beloved Dr. Seuss, The 5,000 Fingers of Dr. T is a musical fantasy that delves into the mind of Bart Collins (Tommy Rettig) a young boy who hates playing the piano. One night his nightmare takes him to a surreal land run by a maniacal piano teacher. This tyrant owns a gigantic piano which he forces Bart and 499 other boys to play (with their 5,000 fingers). However, not all hope is lost; with the aid of a plumber named August Zabladowski (Peter Lind Hayes) the boy creates a noise-sucking machine that destroys the mega-piano and sets the boys free.
