In the first live-action Dr. Seuss feature, young Bart Collins, lulled to sleep by the monotony of his piano lessons, dreams of a castle ruled by his piano teacher, the eccentric Dr. Terwilliker. Dr. T is determined to prove that his "Happy Fingers Method" of teaching piano is the best method in the world. Having banished all other musical instruments to the dungeon, Dr. T lures 500 reluctant little boys to perform in a colossal concert on the grandest grand piano ever built. Filled with surreal landscapes and the tongue-twisting rhymes for which Dr. Seuss is famous, this is fantasy entertainment at its best.
