The plot of the movie UNKNOWN is like something out of a Cornell Woolrich pulp yarn: a guy gets in a car accident, spends four days in a coma, then wakes up and finds out that he has no identification, his wife claims she never saw him before and says she's really married to some other guy with the same name, and nobody believes our hero's story. To make things worse, he's in a strange city, and mysterious assassins are trying to kill him. Paranoia abounds.
Well, there are a lot more complications before everything gets straightened out, and to be honest, this is one of those movies where I was never sure if the plot completely made sense. But if you don't think about it too hard, UNKNOWN is fairly suspenseful and entertaining. I saw a lot of the twists coming, but not all of them. Liam Neeson has become a fairly effective, if a little bit stodgy, action hero, and the chases and fight scenes in this one are well-staged, so you can tell what's happening most of the time. That's pretty refreshing in this day and age. This isn't a great movie, but it's an enjoyable one.
