Good twist to an old plot

Rating: 8/10 (7 July 2011)

A man (Liam Neeson) is in a horrible accident, and when he recovers, no one knows who he is, including his wife, in "Unknown," a 2011 film starring Liam Neeson, January Jones, Diane Kruger, Aiden Quinn, and Frank Langella.
We've seen this plot, or a derivation thereof, many times: the man who disappears and everyone denies his existence to the person who accompanied him (So Long at the Fair, Dangerous Crossing), or the man who suddenly isn't who he says he is (The Net). The plot of "Unknown" is the latter, and Dr. Martin Harris (Neeson) attempts to investigate why someone (Aiden Quinn) is now Dr. Martin Harris and with his wife (January Jones). To do this, Harris must first find the taxi driver who saved his life (Kruger). Meanwhile, he desperately tries to reach a professor (Frank Langella) back at his college who can verify his identity.
This type of film, when done well, as this one was, moves quickly and has lots of actions in order to cover up the plot holes. There usually are some, but if the film is good, one doesn't mind. I have to say I really enjoyed this film, filmed mostly in and around Berlin. Good performances, very exciting, a couple of dandy car chases, and a neat twist. Highly recommended.
