Clock Cleaners (1937) ****

Mickey, Donald and Goofy are cleaning a medieval clock on top of a high gothic tower. Donald entangles himself in coils and springs, Goofy puts his head inside a tolling bell and Mickey chases a stork. There are some nerve-wrecking, high-altitude acrobatics when Goofy looses his balance and walks a tightrope between a blue sky and a certain death. A funny, exciting and superbly animated classic from Disney's most productive and innovative period.
