"Unknown" is another great thriller with Liam Neeson with a surprising plot point. The intriguing story seems to have flaws, but when the mystery is solved, everything has an explanation. Everything works in the thriller: performances, cinematography, music score and specially the twist.
The fifty-nine year-old Liam Neeson is impressively youthful and fits perfectly to the role of a man that loses part of his recollections, and the gorgeous Diane Kruger is excellent as usual. Despite their difference of ages, they are are convincing as a couple. My vote is eight.
Title (Brazil): "Desconhecido" ("Unknown")
