""We decided to dig deep and pay for television ads we weren't planning to buy because we wanted to make the point that Fox News is out of the mainstream," the movie's director, Marshall Curry, told The Post, adding that he believed the network's rejection of the ad was politically motivated. "It says something that some news channels trust their audience to interpret American history while Fox distrusts its audience and doesn't think it can do that." A spokesman for MSNBC said the company initially rejected the ad because an NBC UNiversal standards group deemed the content too provocative. But the group then gave the filmmakers notes on potential changes that would make the ad acceptable for its airwaves, particularly saying the ad would need context before diving into the Nazi footage. The filmmakers returned with a version that included a title card explaining this was part of an Oscar-nominated film. "We wanted to make sure viewers had full understanding and appropriate context of this ad. And the filmmakers were open to feedback to make a change," the spokesman, Joe Benarroch, told The Post. A CNN spokeswoman did not immediately reply to a request for comment. Asked about the new developments, a Fox News spokeswoman re-sent a statement from earlier in the week by president of ad sales Marianne Gambelli which said the “ad in question is full of disgraceful Nazi imagery regardless of the film’s message and did not meet our guidelines.”"
