"After the war years the studio made this beautifully fluid experiment in animation, a remarkable achievement before computers were born. The film shows how the union of the material and spiritual natures of man can lead to fulfilment. John Halas with the Hungarian designer Peter Foldes produced and directed Magic Canvas with an original score by Matyas Sieber, a student of Bella Bartok."

"Berkeley's choreography is important less for its movement of the dancers than for its movement of the camera. To overcome the limitations of sound stages, he ripped out walls and drilled through ceilings and dug trenches for his film crews. When a desired effect could not be accomplished with traditional film equipment, he had his budget expanded to include costs for developing custom rigs. His innovations explored ideas that the stationary camera could not. He wanted to take the audience through waterfalls and windows. He wanted lines of dancers to fall away to reveal scenery that in turn would fall away to expose an even larger setting. His dreams were big, but his determination to see them actualized was even bigger.
Even his worst attempts resulted in eminently watchable movies of exhilarating movement, but his best efforts produced startling effects that bordered on surrealistic dream states. In the quintessential Berkeley films Footlight Parade (1933) and 42nd Street (1933), cameras mounted on tracks are sent soaring past a multitude of dancing legs, flailing arms and orchestra instruments. In all, he directed more than twenty musicals, including an underwater sequence with aquatic star Esther Williams."
