Jaume Collet-Serra is heading into the unknown…

The 47-year-old Spanish filmmaker is set to direct TNT’s one-hour drama Unknown, which is being developed based on the 2011 Liam Neeson action-thriller box office hit.

Directed by Collet-Serra and produced by Dark Castle Entertainment, the film told the story of Martin Harris (Neeson), a doctor who lost his memory after a car accident and woke up to find his identity taken and the target of mysterious assassins.

In addition to directing, Collet-Serra is also attached to executive produce the series, which would pick up after the events of the film and follow a new lead character that is thrust into a mind-bending adventure full of twists and turns.

Sean Finegan will write the pilot and will executive produce.

TNT has had recent success with series based on filns. Out of its three current drama series, two, veteran Animal Kingdom and sophomore Snowpiercer, both were offshoots from features. TNT’s third series, Claws, is headed to its final season this summer.

The Unknown movie was written by Oliver Butcher and Stephen Cornwell. It was adapted from the 2003 French novel by Didier Van Cauwelaert, published in English as Out of My Head. Released in February 2011, the film grossed $136 million on a $30 million budget.

Collet-Serra’s other credits include House of Wax, The Commuter, Run All Night and Orphan.
