After a serious car accident in Berlin, Dr. Martin Harris (Liam Neeson) awakes to find his world in utter chaos. His wife (January Jones) does not recognize him; another man is using his identity, and mysterious assassins are hunting him. The authorities do not believe his claims, and he must go on the run alone. With an unlikely ally (Diane Kruger), Martin leaps into a perplexing situation that will force him to discover how far he is willing to go for the truth.

2.5/4

Along with wanting humor, Unknown’s lacking sense of romance leaves the audience with nothing to root for except the promise that, by the end, Neeson will deliver some knockout blows to the bad guys.

This is a by-the-numbers thriller, in which nothing is what it seems, but nothing is what it seems in pretty much the way you’d expect, if that makes sense.

Liam N is a one character pony and when it works, it works. Here it works. A good story with a solid pace. It's entertaining and is a solid addition to a well walked genre.
