Twentieth Century Fox acquired the action thriller spec Narco Sub from David Guggenheim with Tony Scott attached to direct. Simon Kinberg’s Genre Films is producing with Tony and Ridley’s Scott Free shingle. Guggenheim developed the script with Kinberg and it has become a priority at Fox which is home to Scott Free and Genre. Described as reminiscent of Scott’s Crimson Tide and Man on Fire, plot for Narco Sub involves the semi-submersible crafts South American drug cartels employ to smuggle cocaine into the U.S. Tony Scott last directed Unstoppable for Fox with Denzel Washington starring. Kinberg is writer/producer of Fox’s This Means War as well as a producer on the just wrapped Abraham Lincoln: Vampire Hunter and Neal Blomkamp’s Elysium. Guggenheim has a bunch of works in progress. His script Santiago based on a pitch Fox bought last year is out to filmmakers with Kinberg producing. Guggenheim also has Safe House opening February 10 with Washington and Ryan Reynolds. Also in post is Guggenheim’s spec project Medallion with Nic Cage directed by Simon West from Millennium Films.  McG also just signed to direct Guggenheim’s Puzzle Palace for Summit, and Guggenheim just sold another pitch 364 to Universal for Ron Howard to direct. Steve Asbell will oversee Narco Sub for Fox, Michael Costigan and Elishia Holmes for Scott Free and Aditya Sood for Genre Films. Guggenheim’s agent is David Boxerbaum and manager is Adam Kolbrenner at Madhouse.
