Film: Unknown (2011)

Unknown is a conspiracy action-thriller film released in 2011 and starring Liam Neeson, directed by Jaume Collet-Serra. The film is based on the 2003 French novel Hors de moi, published in English as Out of My Head, by French author Didier Van Cauwelaert.
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.

This film provides examples of:

  • Always on Duty: Nurse Gretchen seems to be personally assigned to Martin's case.
  • Amnesiac Dissonance: Despite his heroic new identity, Martin learns he used to be a professional terrorist/mercenary-assassin before the accident.
  • Arab Oil Sheikh: Prince Shada is the sponsor of the biotechnology conference, and is a rich, adventerous and idealistic guy who wants to support genetically engineering food to help feed the world's growing numbers of starving people.
  • 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.
  • Asleep for Days: Martin wakes up at the hospital after a four-day coma.
  • As Long as It Sounds Foreign: The Saudi prince is named 'Shada' which is not an Arabian name for men nor is it for women. The name has no meaning at all in the Arabic language. There is, however, a feminine name close to it, which is (Shatha).
  • Badass Bystander: This movie may be full of highly-trained international assassins, but the person with the highest on-screen kill count is still Gina the cab driver-turned-waitress.
  • 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).
  • Becoming the Mask: At the end of the film, it is revealed that Martin Harris doesn't really exist, and that "he" was merely a cover story manufactured by a shadowy assassination organization. The other man whom Martin sees taking his place after the accident is actually "Martin"'s "replacement". Martin began to believe that he was the identity of his cover story after suffering head trauma during the car crash.
  • Better to Die Than Be Killed: Jürgen, though the threat of betraying contacts might also have played a part.
  • Big Damn Heroes: Gina does it twice, as Hoist by His Own Petard and Car Fu explain.
  • The Book Cipher: Prof. Bressler's passwords are obscured by an Ottendorf cipher.
  • Car Fu: Gina does this with her taxi when Martin is captured and is going to be killed by the terrorist agent and the agent's boss, Martin's employer Rodney Cole.
  • Casting Gag: Neeson and Quinn played best friends in Michael Collins.
  • Chase Scene: The car chase is memorable.
  • Coincidental Broadcast: When in hospital, Martin turns on the TV which broadcasts a news report about the Biotech summit, which helps to jog his memory.
  • Conveniently Timed Attack from Behind: When Martin is about to be strangled by the hitman at Gina's place, Gina comes to his aid and rams the syringe into the hitman's neck.
  • Cool Car: The Sheik's Mercedes-Benz SLS.
  • Cool Old Guy: Jürgen.
  • Covers Always Lie: The DVD cover, as well as a poster for the movie, show Liam Neeson with a gun in his hand. Never, in the whole movie, does he hold a gun.
  • Cyanide Pill: When Professor Cole goes to see Jürgen, Jürgen empties a sachet of cyanide into his tea and drinks it when he realizes that Cole is not all he seems, and to keep Martin safe.
  • Deadly Road Trip: Being in Berlin, there's no family or friends to vouch for Liam Neeson.
  • Dead Star Walking: Frank Langella portrays a character who dies shortly after being introduced.
  • 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. She's in on it.
  • Every Car Is a Pinto: The black van, that Gina pushes down the parking ramp, goes up in flames.
  • Eye Cam: Used for the scene where Martin wakes up at the hospital. See Unfamiliar Ceiling.
  • Fake Memories: Accidentally, Martin's only memories remaining after the Tap on the Head are fake ones derived from his cover identity.
  • Flashback Effects: Probably overused, including epileptic editing, sepia-tone and dutch tilts.
  • Follow the Leader: The taxi chases, amnesia, European accomplice and the "I'm an assassin" twist make it look like the film was cribbing a lot of notes from The Bourne Identity.
  • Forgot the Call: After the car accident, Martin wakes up with no memory of his mission.
  • Former Regime Personnel: Jürgen.
  • Four Eyes, Zero Soul: The main assassin, who is bespectacled.
  • Gambit Roulette: The villains' plan depends on Professor Bressler bringing a laptop with some very secret and highly important files in it to a party for no good reason, as well as said extremely important files having no backups at all and there being no colleagues he may have shared his knowledge with.
  • Government Conspiracy: A good deal of hard work went into "erasing" Martin Harris after his accident.
  • Hero Stole My Bike: Gina steals a taxi cab to pursue the baddies who just kidnapped Martin.
  • Highly Visible Password: When Liz types in the passwords, they are visible in plain text. And they are using spaces.
  • Hoist by His Own Petard: An assassin tries to inject something in Gina... and she ends up doing it on him instead as he attacks Martin.
    • Liz gets killed by the Time Bomb she helped planting herself.
    • Martin does this at the end, where he ends up preventing a heist that he planned for months, loses millions he could have gained from selling information and ends up killing his associates simply because he suffered a head injury.
      • 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.
  • Identity Amnesia: Martin awakens from a coma after a car accident only to find that no one, not even his wife, recognizes him. He then starts to question his true identity.
  • Impairment Shot: When the other Martin shows Neeson's character the photo of him and his wife, the latter blacks out and the camera takes his view as he sinks down to the ground.
  • Information Wants to Be Free: The assassins' goal is to prevent the open-source release of a new variety of corn on behalf of agribusiness giants.
  • Insistent Terminology: The fact that Harris would always add "doctor" before his name made him seem really insecure. Might be Fridge Brilliance in light of The Reveal, since Neeson's character learned everything about his persona through pure memorization, and for the reasons explained in the Artistic License – History entry, that may have made him more comfortable repeating the phrase the way he absorbed it.
    • Played straight to the extent that a blow to the head effects memory and another one restores it in somewhat contrived fashion.
  • Is This a Joke?: Martin says it quite early.
  • It Was a Gift: Martin always carries a book from his father with him. Also his watch which is a gift from Liz. Turns out both items are planted as part of Martin's cover identity.
  • Just Eat Gilligan: Abduct Harris and hold him in a room until the assassination attempt is finished. Or even make peaceful contact with him, explain what happened and attempt to integrate him back into the terrorist cell.
  • Karma Houdini: Martin exposes himself to be responsible for planting the bomb 3 months earlier but walks away scot-free.
  • Kick the Dog: The first kill that we see onscreen is performed by the assassin when he goes to the hospital. He brutally breaks the neck of the nurse who had earlier given Martin the number of Jürgen, saying that he could help him.
  • Laser-Guided Amnesia: The amnesia conveniently suppresses all memories of Martin's real life from the past 50-60 years, and retains a meager 0.1% that correspond with a fake persona her recently adapted. Also, Martin keeps his superb driving skills, but not his combat skills ... until the end.
  • Magical Negro: Biko, who helps Martin to find Gina. And he did not die first.
  • Missed Him by That Much: In several scenes at the art exhibition, Martin manages to pass by the mobster unnoticed by an inch.
  • Mobstacle Course: In the on-foot chase scene through the hospital, the assassin is constantly blocked by people in his path, which prevents him from catching on to Martin.
  • Monumental Damage: As mentioned above, the Adlon Hotel via the bomb hidden in one of its suites.
  • Mr. Fanservice: Liam Neeson obviously. The man still has the looks, the charm, and when he starts being tough and manly, the ladies go Squee!!!
  • Murder, Inc.: Section 15, Martin's employer, is one of these and will kill just about anyone for the right price.
  • My Card: The doctor handing his card to Martin.
  • My Life Flashed Before My Eyes: Happens to Martin during defibrillation.
  • Neck Snap: The assassin does this to his first onscreen kill, Martin's nurse at the hospital.
  • Oh, Crap:
    • Martin practically wears this expression permanently throughout the whole film.
    • Also, Herr Strauss, after seeing that Martin was indeed at the hotel three month ago.
    • Don't forget Liz's face when the bomb's timer runs out.
  • 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. Later, it is revealed that this was a posed studio shoot and that Martin and his "wife" are merely terrorist agents.
  • The Password Is Always Swordfish: Never derive passwords from details of your personal lives. Professor Bressler uses latin names of plants connected to his twin daughters' names as passwords for his highly sensitive data.
  • Pre Ass Kicking One Liner: "I didn't forget everything! I remember how to kill you, asshole!"
  • Properly Paranoid: Prof. Bressler is taking his laptop to one of the conference receptions. When he has to leave it at the wardrobe, he is feeling quite uneasy about this, bearing to let it hang there unattended only for a few minutes. What he doesn't suspect though is that the important data on it gets stolen via advanced spy technology rather than outright physical theft.
  • Pursued Protagonist: The film is almost a Genre Throwback to the action-thrillers of the 80s-90s that featured Harrison Ford running away from his pursuers, such as The Fugitive.
  • Race Against the Clock: The bundle of plastic explosives planted in the hotel suite to kill Professor Bressler has a digital readout attached, even though it is planted inside the wall where it can't be seen. Liz tries to disarm the bomb, and it looks like she might do it, but is a couple of seconds late as it explodes and kills her, atomizing her and taking out a large chunk of the Adlon Hotel.
  • Revealing Coverup: The plan of the bad guys would have gone a lot smoother if they hadn't been so intent on killing Harris. At one point, Harris is even ready to give up, convinced he must be crazy... then the assassins try to kill him and confirm all his suspicions.
  • Right Through the Wall: At Gina's place, we hear noisy sex from the next room which leads to an awkward moment between Martin and Gina.
  • Ripped from the Phone Book: Harris does this at one point.
  • Sacrificial Lamb: Nurse Gretchen.
  • Sacrificial Lion: Jürgen.
  • Shoe Phone: The USB stick attached to Liz' wristband.
  • Shower of Love: Under MRI, Martin has foggy flashbacks of making love to his wife in the shower. We only see their heads and shoulders, 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.
  • Significant Sketchbook: Gina has one.
  • Slashed Throat: The other Martin gets killed this way.
  • Slow Motion Fall: Of Martin in the taxi cab going off the bridge and into the water.
  • Smug Snake: Martin B and arguably also Liz who doesn't do much sneering but is definitely overconfident.
  • Sorting Algorithm of Deadness: The henchman snaps the neck of the nurse, but doesn't bother to finish off his intended target. Of course, the lethal injection plan fails and the hero gets away.
  • Speak In Unison: The two Martin Harrises find themselves in a Spot the Imposter situation, start to reiterate private information about Martin Harris, and end up doing so in unison. In the end it makes perfect sense: Both of them are fakes and have rehearsed all the personal facts about Martin Harris in exactly the same way.
  • Spot the Imposter: Professor Bressler finds himself in this situation when facing Neeson's character and his doppelganger together at the lab. He chooses to believe the other Martin who is able to produce a drivers license.
  • Strapped to an Operating Table: The assassin ties Martin to a stretcher at the hospital in order to kill him with an injection.
  • Time Bomb: With a 5 minutes countdown.
  • Tomato in the Mirror: After awaking from his coma, people around Martin don't remember him anymore and he starts questioning his sanity.
  • Too Dumb to Live: Liz. Having her face linked to the explosion and destroying her cover might have been bad for her but presumably not as bad as being blown up.
  • Train Escape: Martin notices that he is being followed but manages to escape his pursuer by boarding a car at the subway right before the doors close up.
  • Trapped in a Sinking Car: Due to a freak accident in Berlin traffic, Martin's taxi goes off a bridge and into the river Spree. He hits his head on the window and goes unconscious as the car sinks deeper and deeper into the water. Gladly, his taxi driver is a Bad Ass Bystander and manages to free herself and then pull Martin out through the cab's rear window.
  • Unfamiliar Ceiling: Martin wakes up at the hospital after been Asleep for Days. The ambient sounds are muffled at first and the camera mimics his eyes slowly opening and adjusting to the brightness of the room.
  • Villain Ball: The bad guys replaced their missing comrade a day or two after he disappeared, made no attempt to help him, and began killing everyone around him. They probably would have succeeded if they had made some effort to find him after he disappeared, or even stuck with their plan, backup included, and simply ignored Martin.
  • The Voiceless: Jones, the hitman that gets Car Fu'd by Gina, doesn't have a speaking part.
  • Wham Episode: Several twist moments, the first of which being Liz denying ever knowing Martin, and things continue to go "wham!" from there.
  • Worthy Opponent: Jürgen for Cole.
  • Why Don't Ya Just Shoot Him?: Presumably due to Complexity Addiction. Instead of killing Martin instantly at the hospital, the assassin takes his time with him and starts to inject a slow-dripping poison, which buys Martin enough time to escape.
  • X Meets Y: Nowhere Man meets The Bourne Identity meets Total Recall (1990). Or Flightplan tries to meet Bourne with a sprinkle of Salt, but they miss each other by seconds.
