Joel Edgerton has joined Kathryn Bigelow's currently untitled Osama Bin Laden film. The actor was previously involved in but not officially part of the cast.

The film revolves around the Navy SEAL team that tracked and eventually killed bin Laden.

Many of the roles for the project are still open, including a female reporter embedded with the SEAL 6 team. There is a lot of controversy with the subject matter and how the story came to be. The chairman of Homeland Security announced Thursday that the Dept. of Defense and the CIA were investigating whether classified information about the killing of bin Laden was released to Kathryn Bigelow's team. They did verify that an investigation is taking place.

The project is expected to go into production next month with a Dec. 19 release date.
