We first reported on the project back in November 2011, when late filmmaker Tony Scott was attached to direct. Joe Carnahan was rumored to be circling the project in February 2013, and we reported in October that Doug Liman (Edge of Tomorrow) was in early talks to direct, although it doesn't seem that a deal was ever reached.
