'Hidden City' has become another good example how British films of the eighties have disappeared without a trace. Having found a rare video copy this film I have had the chance to reassess this possible lost gem. Cassie Stuart plays Sharon, a mysterious girl who turns up in the life of lecturer, Charles Dance with a mysterious piece of film placed at the end of fifties public information film. What unfolds is a genuinely interesting look at how Governments have so many secrets they can sometimes get lost. What is also interesting is how this gives an insight in to the early work of writer Stephen Poliakoff and how he still follows many of these theme in his later work more critically acclaim work. Unfortunately 'Hidden City' has dated in it's look and the plot just fails to hit the target. However it is certainly worth looking out for because just like the two leading characters the viewer is drawn into the film's theme of intrigue and mystery hidden in the bowels of London.
