A biochemist and his dishy wife arrive in Berlin for a conference at which a scientist and his controversial Arab funder will announce breakthrough research. While his wife checks into the hotel, he grabs a cab to return to the airport for his briefcase, left at the curb. En route, an auto accident puts him in a coma, from which he awakes four days later without identification and with gaps in his memory. He goes to the hotel: his wife refuses to recognize him and another man has claimed his identity. With help from a nurse, the cab driver, a retired Stasi agent, and an academic friend, he tries to unravel what's going on. Is the answer in the briefcase? Written by <jhailey@hotmail.com>

Did You Know?


The digital camera which Rodney Cole (Frank Langella) uses to take photos of the two "Martin Harris" assassins and Elizabeth is actually a Canon EOS 7D.

For some reason the entire scene was horizontally reversed but the Canon trademark was digitally corrected in post production so that it read "Canon" correctly. The EOS 7D in real life, has the rotary control wheel on the right side of the camera whereas in the flashback scenes, the control wheel appears on the left side of the camera. The information on the camera's LCD screen are also reversed, as if in a mirror. See more »

Crazy Credits

The opening credits are shown as clouds being viewed from an airplane blow past... not so crazy, except that it actually makes one of the credits unreadable. See more »

Bourne Identity meets The Commuter in The Twilight Zone
3 January 2021 | by Instant_PalmerSee all my reviews

Über talented ensemble of actors and the trademark style of the director delivers on-the-edge-of-your-seat suspense, despite a preposterously convoluted story.

Director Jaume Collet-Serra's ('The Commuter') surrounds the mature action star with an ensemble of actors who deliver superb performances.

It all sets up to be a first-rate suspense film, except the story itself is like one of the more fantastical types Rod Serling might have used in his 'Twilight Zone' TV series that press the boundaries of believability.

Unknown delivers on "entertainment", and I recommend seeing the film, but leave your storyline expectations with the cloakroom before viewing.

Note that Collet-Serra uses a similar style of suspense-film story telling seven years later in 2018's 'The Commuter', once again teaming with Neeson in the lead role - if you liked that movie, you will like this one as well.
