Under Suspicion apparently flew completely under the radar upon release in 1991, and that's really not all that surprising. The film is actually a very well done little crime thriller; but it features a very simple plot line and plays out almost like a classic film noir (as opposed to a 'cool' crime thriller in the vein of Goodfellas or Reservoir Dogs), and as a result the film doesn't stand out much. It actually seems like it could have been made for television as most of the cast (Liam Neeson aside) will be recognisable to anyone that has seen a handful of British TV shows and it's very modest all the way through. The film takes place in the fifties and we focus on private detective/disgraced former policeman Tony Aaron. Aaron makes a living through the illegal practise of faking affairs in order to beat the strict divorce laws. He begins using his wife for these capers; but is given a shock when his wife and a client are found dead in their room. An investigation into the killings ensues, with our detective as the prime suspect.
The plot is definitely this film's main strongpoint, and it is carried off well. Director Simon Moore does a good job of getting his audience interested in the characters, which allows him to weave the simple, but twisted tale. Liam Neeson won some award for his portrayal of the central character, and it is a really good performance. This sort of role can often be difficult for actors to play because the character is essentially scum, but we do feel for him; and this is thanks to the charismatic and warm performance. The ensemble cast is rather impressive and, as mentioned, many British viewers will recognise a lot of faces. The mystery is constantly intriguing and we are made to wonder who has committed the crimes. It does have to be said that the final third of the movie not as interesting as the first two; but all in all, this is a well worked and interesting little thriller that is rounded off by a strong ending. I wouldn't recommend anyone goes out of their way to see this film; but it's certainly worth a look if you do find a copy.
