Based on the best selling novel by Harlan Coben this is how a thriller should be made. If you thought Jack Bauer had bad days wait till you meet Dr. Alex Beck (played superbly by Francois Cluzet) the film starts with him along with his wife spending sometime by a lake when she and then he are attacked, she is murdered and he is put into a coma. Skip eight years into the future and although never forgetting his wife's memory he has to a certain extent rebuilt his life. Then things start to turn, when two bodies are discovered buried near the lake and certain evidence suggest a link to Alex and the unsolved case of his murdered wife, suddenly it looks like he is in the frame, again. Then Alex begins to receive e-mails from an anonymous source at first but which seem to be coming from his wife, could she still be alive? And if so what the hells been going on? At 2hrs 11mins this isn't by any means a short film but it is handled so well by director Guillaume Canet that not once did I even notice the time, from the moment the story hooks you it never lets go right up to the end. As Alex starts to dig deeper and deeper to try and uncover the truth you are with him all the way discovering things as he does and when the whole thing finally unfolds it really is quite breathtaking. This film for me had everything, a brilliant script, a seasoned cast, twists and turns, Jeff Buckley's 'lilac wine' used to amazing effect (you will know what I mean when you see it) stunning cinematography, complex subplots that never once get too confusing, it truly is one of the most enjoyable and intelligent films I've seen for a long time.
