Dr. Martin Harris (Liam Neeson) awakens from a coma with amnesia. He remembers enough to head back to the hotel he’s staying at in Berlin. His wife eyes him frostily and produces a new husband (Aidan Quinn), parading as Dr. Martin Harris. The new Dr. Harris whips out a driver’s license and wedding photo to prove it. Even a Google search confirms Quinn is Dr. Harris. Making matters worse, Neeson is being followed by shifty Europeans in black SUVs. Unknown is chock-full of cheap thrills: car accidents, eye-gouging, bloodied bodies, an explosion. It’s a lot like The Bourne Identity, but clunkier. It tosses terrorism and bioengineered corn in the hopper and churns out a headache-inducing genre flick, complete with extreme close-ups, shallow focus, and rapid cuts that make you want to rip the camera from director Jaume Collet-Serra’s hands and zoom out.
