Liam Neeson in action-packed 'Unknown' trailer

Liam Neeson is back in action in "Unknown" (formerly known as "Unknown White Male"), and this time, he's after his own identity. The film directed by Jaume Collet-Serra opens Jan. 7, 2011.

A first feature trailer is now online, and you can watch it below. Looks action-packed for sure, and a little mysterious as well. Hopefully it's as fast-paced and crazy as "Taken," Neeson's recent action thriller.

Th story of "Unknown" follows a doctor (Neeson) who slips into a coma after a car accident while on vacation with his wife in Berlin. When he wakes up, he realizes he's been replaced by another man.

January Jones, Frank Langella and Diane Kruger co-star. Collet-Serra recently directed "Orphan."
