Of all the rumored and speculated films revolving around WikiLeaks founder Julian Assange — refresh your memory by clicking here and here — one that seems to be building very positive momentum is the recently-announced production at HBO Films, to be directed by Charles Ferguson, director of the Oscar-winning documentary Inside Job.

Previously, the producing lineup was thought to include Audrey Marrs, Joshua Maurer, Alixandre Witlin, and David Stern, but apparently more names have become involved. Not only have Kathleen Kennedy and Frank Marshall been recruited by HBO Films to produce, but Rowan Joffe, screenwriter of the striking and unusual crime film The American, has been pegged to write the screenplay.

There’s no word yet on when production might begin, but we’ll keep our eyes peeled on this project — as well as the other Assange-related projects — as the details roll in.

What do you think of the hiring of Joffe?
