Fox TV Studios, division of News Corp.’s 21 Century Fox and a sister company of Fox News, is in discussions with NBC about coming on board to produce the network’s recently announced 4-hour miniseries Hillary, about Hillary Clinton, that has Diane Lane attached to star as the former First Lady and Secretary of State. I hear the talks, first reported by the New York Times, are preliminary, with the two sides far apart. The economics of TV movies and miniseries are challenging, which is why very few production companies take on such programs these days. That includes NBC’s own studio, Universal TV, which would not produce NBC’s longform projects, including Hillary. The Clinton mini, to be written by Courtney Hunt, already has become a lightning rod of controversy, with Republican National Committee Chairman Reince Priebus threatening to yank primary debates from NBC and NBC News Chief White House Correspondent Chuck Todd calling the mini “a total nightmare” for the news division.
