Unknown (Blu-ray)

A man claiming to be Dr Martin Harris awakes in Berlin hospital with severe head injuries and very little knowledge as to how he got there. The doctors inform him that he has been in a coma for four days after surviving a near fatal car crash. Attempting to piece together the incidents leading up to the accident, he discovers that his wife no longer recognises him and another man has assumed his identity. Now the only thing standing in the way of him and the truth is a deadly team of trained assassins who will stop at nothing to have him killed. It’s time for Dr Harris to face his identity, his sanity and take back his life… by force. Starring Liam Neeson (Taken, The A-Team), Diane Kruger (Inglourious Basterds, Troy) and January Jones (Mad Men, X-Men: First Class), Unknown is a gripping mystery pumped with visceral action and an explosive revelation around every twist.
