It's funny watching the elements come together in this complicated scam. On one hand, the set-up isn't quite as complex as it seems, but there's an easy sense of fun in every exchange.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

The acting in this movie is really good.

I only watched this picture because of my current obsession with Charles Dance. It's a very strange film, rather too artsy and noir for my taste, but in general a pretty good picture.A few items: far too much is made of the "hidden city" component. Any older city has subterranean tunnels and chambers. Disused subways, dry drains, utility shafts and connectors, power cable channels, catacombs, and sewage pipes form a veritable honeycomb beneath a city's surface. Not secret so much as not relevant to the daily life of ordinary people. That these areas might be useful for file storage is sensible and efficient. The more intriguing mystery for me was why the writers writers (who otherwise did an excellent job) failed to give us explanations to these questions: Why would an intelligent, sophisticated, educated man disregard several days' worth of scheduled meetings in order to assist a complete stranger in an ill-defined quest for information of questionable value?Why, having learned the mysterious government secret, do the pair do absolutely nothing with what they've learned? It's implausible that anybody would go to so much trouble merely to satisfy idle curiosity.And finally, why do the pair decide to continue rummaging for secrets?On the plus side, "Hidden City" does include a very excellent performance by Charles Dance. I think that one of the more difficult challenges for an actor is speaking lines that convey information the audience needs but would never be uttered in real-life conversation. The film contains an astonishingly large number of such lines, and Dance delivered them so naturally that only when I'd finished watching did I realize. In fact, I can't think of a better example of that sort of acting. Well done, Charles Dance!

What a strange movie. The story is amazingly thought-provoking and intriguing. Think of all the hidden secrets a city like London hides beneath it's surface? All the archives of wartime experiments, government mysteries, documents and information never meant for public eye.You have a young woman trying to convince a statistician (?) played by Charles Dance that there are hidden messages or clues of a bigger picture in some wartime archive films.The story sadly never quite uses all of it's potential. It's interesting all the way, but you're never really sure what is going on until the very end and the motivations of the characters are left a bit unknown. They're basically just intrigued and driven by pure interest rather than a real cause.What makes the movie a bit messy and difficult to follow, is the fact that there are a few separate leads they're following, the archived films and a few documents they find at a waste dump. You also have people trying to catch them, but you're not really sure why. At least I was left a bit puzzled of what's going on at times, but maybe that was the point. You never know what you find, if you just look carefully.Definitely an interesting story, but the execution is a bit flawed and dated. It's got a very strong late 80s vibe to it and it's a bit of an artsy one. Someone might call this a "strange one", but definitely worthwhile if you catch it somewhere.

Of all Poliakoff's work on film, this is probably the most underrated and often missed , and is one of his two best works from the 1980s.This is an interesting and thoughtful look at the workings of one aspect of modern government, which was well-received at the time and premiered at the Venice festival, but has become criminally and unjustly difficult to find. A proper DVD reissue is long overdue here.Charles Dance produces a typically strong performance with direction, performances and casting all solid ; this was a part of the important Film on Four strand that helped keep British cinema alive during some of its lowest points of the 1980s.

'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.
