Unknown

With 2008's kidnap thriller Taken, Liam Neeson proved himself surprisingly adept as a full-on action lead. Ok, he's not Ethan Hunt leaping balletically from the epicentre of blossoming fireballs, or even Jason Bourne flitting across rooftops like a gravity defying wildebeest. But he is a tough, likeable presence whom we completely believed as a man who will be rescuing his daughter no matter how many heavily armed goons you throw at him.

Now, in Unknown, he's showcasing much the same shtick, this time in Berlin rather than Paris, to reasonably gripping effect. You may or may not solve the mystery of his amnesiac doctor's identity before he does, but either way he's an engaging enough screen presence that he's never less than watchable.

Our attention wanders during the final reel as McGuffins are unmasked and conspiracies unravelled in a slightly prolongued fashion, and by people we've very little invested in: this ought to be Neeson's show and Neeson's show alone.
