The first five minutes of this film - set in a national newspaper office as Germany invades Poland - are superb. Unfortunately the rest of the film suffers in comparison and the most interesting character, played by a relatively young and buzzing Ralph Richardson, is killed off far too early. Otherwise it could have rivalled Q-Planes, another Richardson tour de force from a couple of years earlier. Williams is effective but slightly colourless in the lead although Deborah Kerr sparkles. The Rule Britannia v Horst Wessel scene in the bar echoes the more celebrated La Marseillaise v Watch on the Rhine song battle in Casablanca. I wonder which came first?
