Yahoo have just debuted the new trailer for Liam Neeson’s new movie, Unknown. Unknown is directed by Jaume Collet-Serra and as well as Neeson, stars January Jones, Diane Kruger and Frank Langella. This trailer looks great with Neeson waking up after a car accident to discover that his life has been taken over with his wife denying she’s ever seen him before.

It’s scheduled for release in the US February 18, 2011 but no release date has been mentioned for the UK as yet.

Synopsis: Dr. Martin Harris awakens after a car accident in Berlin to discover that his wife suddenly doesn’t recognize him and another man 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, Martin plunges headlong into a deadly mystery that will force him to question his sanity, his identity, and just how far he’s willing to go to uncover the truth.
