Did You Know?


During the shooting and release of this film, Liam Neeson's wife, Natasha Richardson, died from a skiing accident. See more »


After Dr. Harris is pulled from the river and the EMTs are working on him they use a defibrillator on him to attempt to revive him. This is totally inaccurate, as he is covered in water, lying in water, and the EMTs are standing/kneeling in water while using a powerful electrical current. Had this been real then not only would the current have passed through Dr. Harris's entire body but the bodies of the EMTs working on him. Something that anyone familiar with the use of a defibrillator well knows hence the warning "clear" called when ever it is used. See more »

User Reviews

Involving and well interpreted action-thriller
28 February 2011 | by (Italy) – See all my reviews

The movie sounds intriguing since from the beginning and keeps its sense of mystery and intrigue till the end: this is a good quality, once reminding Hitchcock's thrillers, with the difference that in "Unknown" the thrilling aspect cannot be separated from the frenzy typical of action movies. The result is an entertaining, involving pic, never losing its strong and quick rhythm and letting the viewer staying attached to the screen till the end. Set in a depressing Berlin covered by snow, always marked by the sad signs of a more or less distant past, a good photography gets to capture the overall gloomy atmosphere of the story and the mystery of a character whose vicissitudes seem as much incomprehensible as much needing some resolution, and an effective final twist as well. Liam Neeson plays skillfully, although not always sufficiently expressive, he gets to convey the sense of void of someone looking for some identity. A stand-out performance is offered by Bruno Ganz and also Diane Kruger supports Neeson quite well. Certainly not a masterpiece, but worth the ticket.
