From 2007’s Oscar-winning documentary Taxi to the Dark Side to the just released The Dark Money Game, producer-director Alex Gibney has been tirelessly zooming in on the wrongs that need to righted. From Enron to Jack Abramoff, Henry Kissinger’s war crimes to WikiLeaks, Lance Armstrong’s doping to Scientology’s secrets, and Russian oligarchs to the imperial presidency and beyond, Gibney has relentlessly probed and illumined darkness with his camera lens.

The Dark Money Game, the filmmaker’s two-part, four-hour series for HBO and Max, focuses on the corrosive effects of Citizens United v. FEC, the Supreme Court decision that equated speech with money and ushered in a tidal wave of campaign cash, undermining our democracy. Like nonfiction versions of film noir mysteries, Ohio Confidential and Wealth of the Wicked — the two parts of latest Gibney’s hard-hitting documentary — investigate and chronicle the corruption flowing from this subversion of the US electoral and legislative systems.
