(CNN) Publishing hasn't been the only medium to reap benefits from the Trump presidency. Documentaries -- especially those with political overtones -- have also experienced a golden-age-type windfall, evident in strong summer boxoffice for movies like "RBG," with an additional spate of releases due this fall.

Just the next few weeks will see the opening of "Active Measures," director Jack Bryan's meticulous examination of the relationships and history linking President Trump to the Russian government; and "America Chaos," James D. Stern's first-person account -- as a Hillary Clinton supporter -- of the factors leading to Donald Trump's surprising election as the 45th president.

Those projects will be augmented by several more, including high-profile premieres in September at the Toronto International Film Festival: Michael Moore's "Fahrenheit 11/9," a date tied to the 2016 election; Errol Morris' "American Dharma," about Trump administration alumnus Steve Bannon; and Alexis Bloom's "Divide and Conquer: The Story of Roger Ailes," a profile of the late patriarch of Fox News Channel, which has become in the eyes of many political and media observers a near-indistinguishable extension of the Trump communications operation.
