Performers, Cast and Crew:
Los Angeles Times - 02/18/2011
"UNKNOWN is very much in the tradition of smooth Continental entertainments that expertly deliver on audience expectations....UNKNOWN is consistently albeit genteelly thrilling..."
New York Times - 02/18/2011
"The director Jaume Collet-Serra knows is way around multilane roadways, and he and his stunt team squeeze in a few slick car chases..."
Washington Post - 02/18/2011
3 stars out of 4 -- "[A] film that trades the lurid extremes of TAKEN for a more subtle, sophisticated vibe."
Box Office - 02/17/2011
3.5 stars out of 5 -- "Jaume Collet-Serra's tidy, moody thriller ticks along at a fast pace -- like the Autobahn, it's pure Teutonic efficiency."
Sight and Sound - 04/01/2011
"For his first actioner, Collet-Serra attacks the opportunity of a classic car chase, articulately shot and cut, and built in distinct movements."
