Unknown: The star of Taken and The A-Team jumps back into action with brute force! Liam Neeson plays Dr. Martin Harris, who awakens after a car accident in Berlin to discover that his wife (January Jones) suddenly doesn't recognize him and another man (Aidan Quinn) has assumed his identity. Ignored by disbelieving authorities and hunted by mysterious assassins, he finds himself alone, tired and on the run. Aided by an unlikely ally (Diane Kruger), Harris plunges into a deadly mystery forcing him to question his sanity, his identity and just how far he's willing to go to uncover the truth. Edge Of Darkness: The bullet that killed his daughter was meant for Boston cop Thomas Craven. That's what police brass and Craven himself think, but that's not what the investigation finds. Clue after clue and witness after witness, the search leads him into a shadowy realm where money and political intrigue intersect. If Craven wasn't a target before, he - and anyone linked to his inquiry - now is. Mel Gibson stars in his first screen lead in eight years, making Craven's grief palpable and his quest for payback stone-cold and relentless. Martin Campbell (Casino Royale) directs from a screenplay co-written by The Departed's William Monahan. Gibson is back, taking us to the edge...and into the sinister darkness.
