由导演Erik Nelson执导，2017年上映的《灰色国度》，是由Barry Drones,Mason Hendricks,Danny August Mason等主演的记录片片。 　　In 2010 David Crowley, an Iraq veteran, aspiring filmmaker and charismatic up-and-coming voice in fringe politics, began production on his film Gray State. Set in a dystopian near-future where civil liberties are trampled by an unrestrained federal government, the film s crowd funded trailer was enthusiastically received by the burgeoning online community of libertarians, Tea Party activists as well as members of the nascent alt-right. In January of 2015, Crowley was found dead with his family in their suburban Minnesota home. Their shocking deaths quickly become a cause célèbre for conspiracy theorists who speculate that Crowley was assassinated by a shadowy government concerned about a film and filmmaker that was getting too close to the truth about their aims.
