Unknown (2011 film)

Unknown is a conspiracy action-thriller film released in 2011 and starring Liam Neeson, directed by Jaume Collet-Serra. Neeson plays botanist Dr Martin Harris, who brings his wife along to attend a biotechnology conference in Berlin. However, he gets into a car accident while riding the taxi back to the airport to pick up luggage he left behind. When he awakes in hospital, he leaves to find his wife. However, Liz denies knowing who Martin is...and another man is wearing Martin's name tag and claiming to be him is standing right next to her - and she acknowledges "Martin B" as the real deal. In a foreign land for the first time, pursued by mysterious terrorists and with nobody to trust, Harris must get all the help he can find, including from Gina (Diane Kruger) the driver of the cab that plunged into the river and Jürgen (Bruno Ganz), a former Stasi agent-turned private investigator.

The film not only has a Twist Ending, it has twist beginnings, twist middles and twist three-quarters - hence the large amount of marked spoilers below.

Not to be confused with the 2006 James Caviezel movie.

 * Artistic License History: As explained here, what Jürgen stated about the Stasi's methods for distinguishing a liar from a truthteller is the opposite of the Stasi's real-life interpretation: a liar has a pre-programmed version of facts which is difficult to deviate from, while an innocent person will rephrase and reformulate.
 * Bathroom Break Out: The assassins arrive to kill Martin as he is taking a shower, and he escapes onto the roof (sorry ladies, he's wearing a bathrobe).
 * : At the end of the film, it is revealed that Martin Harris  The other man whom Martin sees taking his place after the accident is   Martin began to believe

 * Though lasts for a significant fraction. The other, not so much.
 * Drives Like Crazy: Gina the taxi driver, but only when she really needs to.
 * Dull Surprise: January Jones as Liz, all the time. The audience is meant to doubt her allegiance to good or evil.
 * Fake Nationality: Liam Neeson being a Fake American is traditional. But Diane Kruger is German, the movie is set in Berlin... and she plays a Bosnian.
 * Flashback Effects: Probably overused, including epileptic editing, sepia-tone and dutch tilts.
 * Four Eyes Zero Soul: The main assassin, who is bespectacled.
 * Government Conspiracy: A good deal of hard work went into "erasing" Martin Harris after his accident.

 * Ironically, the assassin conspiracy hoisted themselves up first. Had they not come after Liam Neeson in the hospital, when he was completely confused and starting to believe the head trauma had made him go mad, he likely would have been disoriented and under medical observation long enough for the plan to go off without a hitch. They could have also simply reinvented him as someone who might plausibly have known the fake Martin (who tragically died in the blast,) and set him up in a nice, no-memory retirement. Instead they tried to kill him, setting him on an epic quest to find out who he really was.
 * Information Wants to Be Free: The assassins' goal is to prevent the open-source release of on behalf of.
 * Insistent Terminology: The fact that Harris would always add "doctor" before his name made him seem really insecure. Might be Fridge Brilliance

 * Laser Guided Amnesia: Invoked
 * Magic Countdown: The bundle of plastic explosives planted in the hotel suite to kill  has a digital readout attached, even though it is planted inside the wall where it can't be seen.   tries to disarm the bomb, and   Adlon Hotel.
 * Murder Inc:
 * Neck Snap: The assassin does this to his first onscreen kill,.
 * Oh Crap:

 * Also, Herr Strauss, after seeing that.
 * Don't forget.
 * Once More With Clarity: Martin often has flashbacks of having a picture taken with his wife while on their honeymoon, after she gave him the watch.
 * Pursued Protagonist: The film is almost a George Lucas Throwback to the action-thrillers of the 80s-90s that featured Harrison Ford running away from his pursuers, such as The Fugitive.
 * Pre Ass Kicking One Liner:
 * Revealing Coverup:.
 * Ripped From the Phone Book: Harris does this at one point.
 * Shoot the Dog: The first kill that we see onscreen is performed by the assassin when he goes to the hospital..
 * Shower Scene: Martin has foggy flashbacks of making love to his wife in the shower. We only see their head a shoulder, and besides showing off January Jones' perfect body and nice O-face, this is one of many flashbacks that may clue the viewer in to the truth of the matter - while designed to mislead instead. Clever.
