Here's Why CBS Won't Air Ads for Robert Redford's New Movie Truth

CBS is not happy with Cate Blanchett and Robert Redford's new movie Truth.

According to The Hollywood Reporter, the network has refused to air any advertising for the movie, about a 2004 incident in which a CBS news story about President George W. Bush's military service record was discredited.

CBS said it was not comfortable accepting advertising for Truth due to inaccuracies in the movie that would offend CBS News employees. The network also went on to denounce the movie as an insult to journalists as well as the public.

"It's astounding how little truth there is in Truth," said Gil Schwartz, chief spokesman for CBS and depicted as a character in the movie. "The film tries to turn gross errors of journalism and judgement into acts of heroism and martyrdom. That's a disservice not just to the public but to journalists across the world who go out every day and do everything within their power, sometimes at great risk to themselves, to get the story right."

In the movie, Redford stars as Dan Rather with Blanchett playing producer Mary Mapes. The two were behind a 60 Minutes II story that questioned Bush's commitment to service in the Texas Air National Guard during the Vietnam War. CBS apologized for the story after documents were called into question that could not be verified. Mapes and three executives were ultimately fired. Rather left CBS News in 2006 and unsuccessfully sued the network.
