Harold Perrineau, who starred on Lost as Michael Dawson, will join the Hurt Locker director's next project, which chronicles the hunt for the elusive terrorist behind the 9/11 attacks.
There is no word on who Perrineau will be playing, as the parts in the film are largely being kept a secret for the moment, Deadline reports.
On Wednesday (February 22), it was revealed that Nash Edgerton and Jennifer Ehle have joined the bin Laden project as well, with Edgerton playing a Navy SEAL.
Friday Night Lights star Kyle Chandler signed on to the film earlier this month. He will reportedly portray a CIA agent.
The untitled bin Laden movie is expected to begin shooting soon for a December 2012 release.
