The big screen version of Uncharted: Drake's Fortune is starting to sound less like Raiders of the Lost Ark and more like National Treasure. Director David O. Russell says his upcoming game-to-film adaptation will focus on treasure-hunting hero Nathan Drake (to be played by Mark Wahlberg ) -- as well as his extended family.

The writer-director, who said he is now halfway done with his script, told The Los Angeles Times , "This idea really turns me on that there's a family that's a force to be reckoned with in the world of international art and antiquities ... [a family] that deals with heads of state and heads of museums and metes out justice.""We'll have the family dynamic, which we've done in a couple of movies now," said Russell, whose past films about dysfunctional familes include Flirting with Disaster and The Fighter. "And then you take that and put it on the bigger, more muscular stage of an international action picture, but also put all the character stuff in it. That's a really cool idea to me."Russell also called the urgency of the Uncharted production, a high priority for Columbia Pictures who wants the film out sooner than later, "a locomotive."
