Untitled project has an all-star cast.

‘The Hurt Locker’ helmer Kathryn Bigelow continues to fill out the cast of her forthcoming untitled drama about Navy SEAL Team 6′s long hunt for Osama bin Laden. Not content with boasting an already impressive cast that includes Joel Edgerton, Jason Clarke, Chris Pratt, Jessica Chastain, Mark Strong, and Edgar Ramirez, Deadline reports that the director has enlisted Kyle Chandler (‘Super 8,’ ‘Friday Night Lights’) in the role of a CIA agent.

EW has word of two more great additions to the cast, that of Jennifer Ehle (‘The Ides of March,’ ‘Contagion’) and Nash Edgerton, Joel’s big brother and director of the 2008 thriller ‘The Square.’ While there are no details on what part Ehle will be playing, sources close to the project are saying that Nash will be taking the role of a Navy Seal.

Other actors reportedly involved in the Mark Boal-scripted drama include Idris Elba (‘Ghost Rider: Spirit of Vengeance,’ ‘The Wire’), Tom Hardy (‘The Dark Knight Rises,’ ‘This Means War’), and Guy Pearce (‘Prometheus,’ ‘The Hurt Locker’).

Production on the film is expected to being soon with a release set for December.
