The movie was shot in Australia at Cate Blanchett's request, as she wanted to be close to her family while filming.
Dan Rather praised the film for its accurate portrayal of television news. He particularly liked Robert Redford's portrayal of him as Redford didn't attempt an impersonation.
Actors are only allowed to submit one lead performance if they are going for an Academy Award nomination for a leading role. Cate Blanchett opted to have her performance in Carol (2015) submitted for consideration instead of her equally well-received performance as Mary Mapes in this film. It proved to be the wiser choice, given Truth (2015)'s disastrous box-office performance.
The film starts off quite colorfully but as Mary Mapes finds herself in a more compromising position, the color gradually drains away. Cate Blanchett is also filmed more in center frame to emphasize the walls closing in on Mapes.
Toward the end of the film, when Mary Mapes is talking on the phone to Dan Rather, she is leaning against a bookcase in her home. On the shelf, you can see the autobiography of legendary Washington Post editor Ben Bradlee, called "A Good Life". Bradlee was editor when the Post exposed the Watergate scandal. As in this movie, he had to manage a media disaster when it was discovered that Post writer Janet Cooke fabricated a story about a young drug addict, which won the 1981 Pulitzer Prize. Once the truth came out, the Post returned the prize.
