Mediocre thriller

Rating: Null/10 (6 June 2011)

Dr. Martin Harris (Liam Neeson) and his wife Liz (January Jones) arrive in Berlin for a biotechnology summit. Upon arriving at their hotel, Martin realizes he forgot his briefcase at the airport. He takes a taxicab driven by Gina (Diane Kruger), but on the way to the airport, the cab crashes off a bridge into the river after narrowly avoiding a refrigerator that falls off a delivery truck. Martin is knocked unconscious upon impact, but Gina saves him from drowning before fleeing from the scene. On Thanksgiving day, he comes to at the hospital after being in a coma for four days.Martin returns to his hotel, only to discover that his wife who proclaims to not know him, is with another man who says he's Dr.Martin Harris.
Unknown has a tremendous premise and a great actor in the lead role, Liam Neeson. However, this film did not succeed and the main reason is because of its execution. The plot is, in fact, quite interesting, there's quite a bit of action and the acting is pretty good. And I must say that the twist was not at all what I expected and it will be extremely difficult for anyone to predict it.
Having said that, the way all these bits were put together did not make a very good film. It has a lot of potential but it never really reaches and ends up being a very mediocre thriller. Much inferior to Liam Neeson's last action thriller, Taken, for instance.
6/10
