A planned CNN documentary about U.S. politician Hillary Clinton has been axed. Director Charles Ferguson reveals he has been struggling find sources among Clinton's Democratic Party and her Republican rivals who would be willing to speak on camera about the former First Lady and Secretary of State, so he's been left with little choice but to scrap the project altogether. In a post on his Huffington Post blog, he writes, "When I approached people for interviews, I discovered that nobody, and I mean nobody, was interested in helping me make this film. Not Democrats, not Republicans - and certainly nobody who works with the Clintons, wants access to the Clintons, or dreams of a position in a Hillary Clinton administration. "After painful reflection, I decided that I couldn't make a film of which I would be proud. And so I'm cancelling... "It's a victory for the Clintons, and for the money machines that both political parties have now become. But I don't think that it's a victory for the media, or for the American people." The feature-length documentary had been due to focus on Clinton's career in office and speculation about plans to run for the White House in 2016. It was one of two productions in the works about Bill Clinton's wife - actress Diane Lane is set to portray the politician in a forthcoming mini-series for America's NBC network. The announcements of both projects this summer (13) prompted an angry response from Republican National Committee (RNC) chairman Reince Priebus, who accused network bosses of unfairly promoting Clinton ahead of the next presidential elections. He vowed to boycott the two channels if the film and TV series were not scrapped.
