This minimalist thriller is a one-of-a-kind film with an excellent pedigree; not only is it directed by Robert Fuest, who gave us a minor horror classic in THE ABOMINABLE DR PHIBES, it is also written by two top television writers of the time, Brian Clemens (THE AVENGERS) and Terry Nation (DR WHO). However unlike the various work of the contributors this isn't an effects-driven exercise in flashiness and action; instead barely anything happens in the movie.
The pacing is deliberately slow, and the film as a whole is largely an atmosphere-building exercise with the only action appearing at the very end of the film. The visceral horror aspects are mainly non-existent and instead the film strives hard to create and maintain high levels of suspense and foreboding. The forbidding setting of a rural French landscape is a clever touch and through static camera angles and creepy music we are led to believe that the landscape we see is both alien and dangerous.
Beautifully filmed and with a strong script - with little dialogue Clemens and Nation make sure that every word counts - AND SOON THE DARKNESS is an exercise in realism. As there are no special effects involved the film hasn't dated at all and could be taken for the present day if it wasn't for the minor trappings, i.e. the old fashioned vehicles and hairstyles. Again the realism is strengthened through the matter-of-fact storyline, with large periods of inaction adding to the experience.
The main emphasis is on the murder mystery aspect of the plot, most of the film acting as a whodunit and asking the viewer to guess firstly what happened and secondly who is responsible. The task isn't easy at first, with loads of red herrings and plot twists being thrown in our way, but gradually light will begin to dawn on those who have prior knowledge of these kinds of movies.
The cast is an extremely small one, consisting of only four or five major characters. This adds to the isolated nature of the movie, especially with the language barrier deeply affecting the situation of our leads. Pamela Franklin proves she has grown up a lot since THE INNOCENTS with her mature yet fragile nurse character and her subdued turn is generally spot on. In comparison, Michele Dotrice (SOME MOTHERS DO 'AVE 'EM) is flirty and attractive as her outgoing companion and also makes a favourable impression. Sandor Eles (COUNTESS Dracula) is given a chance to shine as the shifty Frenchman who gets caught up in the events and becomes a prime suspect.
Shots of unkempt farmers staring at Franklin over lonely open landscapes and cars soaring into the distance go a long way in adding to the increasing atmosphere. Despite the lack of violence, murder and bloodshed, horror fans should enjoy this movie through the sheer amount of suspense and atmosphere that it offers. Definitely a thought-provoking and at times gripping movie. A similar offering - but even rarer - followed three years later with DEADLY STRANGERS.
