We reported last month that David Ellison signed on to produce with his sister Megan Ellison. David Ellison's Skydance Productions is responsible for blockbusters such as Mission: Impossible Ghost Protocol and G.I. Joe Retaliation 3D, while his sister Megan Ellison is behind Oscar-nominated dramas such as The Master, Silver Linings Playbook, and Zero Dark Thirty.

The project still does not have a director yet after Justin Lin bowed out in September 2011. It hasn't been confirmed if Arnold Schwarzenegger will return to the franchise.
