Jennings' great wartime work really began with London Can Take It. Along with Watt he made this, the first of the home-front war films to make its mark. A one-reeler shot in haste, the film was of great propaganda value at the time and very successful in England and America. Couched in the form of a dispatch, it tells the story of one night in the first London blitz. What the camera reports (in vivid terseness lit by gun flashes) the commentary underscores with true pathos.
