Ken Annakin's first movie as director is a report on the state of London, two years after Humphrey Jennings' LONDON CAN TAKE IT. It shows a London that has some scars, is suffering a bit from wartime rationing, but has set up a routine of work, play, and war duty that narrator Robert Speaight assures the audience will keep the lights on until the war is over: pigs raised for food in bombed-out basements, music-hall entertainers at communal lunches, the swing shift heading into work at the factory as the lights go out, all these are meant to reassure the audience that London will not falter, so keep your pecker up and do your bit.
Annakin would go onto a long career as a director of commercial fare, eventually moving into spectaculars in the 1960s.
