This century has seen Liam Neeson in real leading roles, when his character "permeates" the whole movie and is strong and quick-witted. Taken 1 and 2 are best known, Unknown has - for some reason or another - remained in their shadow. In my opinion, the script of the latter is much stronger, has more twists-turns and unpredictable moments - me being a fan and active viewer of crime thrillers could not guess what kind of background could Neeson's character Dr. Martin Harris really have. Sequence of the events is logical and chases are visually enjoyable. The ending in general is predictable, apart from the very last scene.

Well, all the cast is excellent, not only Liam Neeson; Diane Kruger and Bruno Ganz are the supporting actors more time on screen and they are really good. In short, Unknown is really worth watching - especially if you have not read spoilers :)

Dr Martin Harris (Liam Neeson) and his wife Elizabeth Harris (January Jones) get into a car accident. Martin survives but when he wakes up, his wife no longer recognizes him and someone else (Aidan Quinn) has taken his place. The world becomes a place of paranoia, and the only person who helps him is the waitress Gina (Diane Kruger).

It's an unusual head scratching premise. It's a mystery as to what the true story is. Is it all in his head? Or is it reality? The pace could be faster in the first half. I wish they didn't push the color spectrum so far to the the blueish green. It's obvious and distracting. Also they need to pair up Kruger and Neeson a lot sooner. As it stands, the movie is split in two. The first is a slow meditating paranoid interior film. The second half becomes a Bourne Identity film. It'd probably improve to concentrate the first half more.

UNKNOWN is one of those silly films which rehashes the same themes and plots of other, better movies in an attempt to make some money, instead of thinking up new, original concepts. At first glance, this seems to be a slightly supernatural thriller about a man being haunted by his own doppelganger, bringing to mind the Roger Moore flick THE MAN WHO HAUNTED HIMSELF. Having just watched the movie, it failed to fulfil any of my expectations and turned out to be a rather unappetising mix of three rather more recent films.

The film it most obviously recalls is TAKEN, the top-notch action flick which reinvented Neeson as an action star. Neeson's trapped in Europe again, fending off various bad guys, although this is far from being an action movie; the fight scenes, unlike those in TAKEN, aren't up to much. Then there are the plot twists and turns, and the whole amnesic storyline which brings THE BOURNE IDENTITY to mind. Thematically, though, I was most reminded of the excellent Roman Polanski thriller FRANTIC, which saw Harrison Ford searching for his missing wife in Paris.

UNKNOWN has a familiar look and feel to its storyline and few things that take place during the running time will come as a real surprise. Neeson is sleepwalking through his role, and Diane Kruger has very little to do, but both of their performances look masterful in comparison to January Jones' excruciating turn as Neeson's wife – seriously, who told this woman she could act? Aidan Quinn pops up in a minor role which makes you wonder what happened to him, and Frank Langella is in the movie even less. The excellent Bruno Ganz has pretty much the same type of mentor/support role as he did in THE MANCHURIAN CANDIDATE remake.

Despite being superficially entertaining during its running time, in the end UNKNOWN fails because of the sheer ludicrous nature of its plot. It holds the attention while you watch, but soon afterwards you sit back and realise that most of the the story is based on contrivance and coincidence. As such, it's certainly not a film you'll be in any hurry to watch a second time around.
