« Besides their sometimes overbearing tone, the main weakness in the films [of the Canada Carries On and The World in Action series] is that the commentary plays the dominant role. Images are used simply to illustrate the verbal argument. The images often represent deceptively what is being said in the commentary. For The Mask of Nippon, for instance, shots of Japanese swimmers in a long-distance competition are used to represent Japanese navy swimmers preparing to sabotage British ships somewhere in the Far East. »
