British scribe Rowan Joffe has signed on to script HBO's untitled WikiLeaks movie.

The project is a co-production with the BBC, and is based on source material that includes Raffi Khatchadourian's 2010 New Yorker article "No Secrets: Julian Assange's Mission for Total Transparency".

The film will tell the story of WikiLeaks, a database run by former hacker and Internet activist Julian Assange and his operatives, whose mission is to collect and disseminate via the Internet private, secret and classified information from anonymous sources.

Oscar-winning documentary filmmaker Charles Ferguson (Inside Job) is attached to direct.

No production date has been set, but the project is coming together rapidly.
