Watch Industrial Britain (1931) Official Trailer

Grierson set out to make "propaganda," and this film--with it's voice-over proclaiming the great value of the British industrial worker, without a hint of ambiguity or doubt--fits that category well. The authoritatarian narrator feels out-of-date and unsophisticated, but the footage is well shot and interesting, and the transparency of the propaganda aspect is almost a reflief at a time when so many films have hidden agendas.
