Ben Bradlee who's portrayed in this movie by Alfred Molina was also portrayed by Tom Hanks in The Post and Jason Robards in All the President's Men. Also his son Ben Bradlee Jr. was portrayed by John Slattery in the film Spotlight.

Hugh Jackman was invited by the real Gary Hart to stay at his home while the two of them got acquainted. Since Hart's wife was recovering from hip surgery and the two of them were sleeping downstairs, Jackman was actually allowed to stay in the master bedroom and sleep in Hart's own bed.

Oddly, the Film never mentions, shows or recreates the famous incriminating dock photo of Donna Rice in a mini skit and sitting on Senator Hart's lap. Though published by the National Enquirer, it was a big nail in Hart's political coffin.

Molly Ephraim and Kaitlyn Dever previously appeared as sisters on ABC's "Last Man Standing."

Sarah Paxton who plays Donna Rice was born in 1988, the year the events depicted occurred.

The film premiered at TIFF (Toronto international Film Festival) in Canada in September 2018.

It reunites J.K. Simmons and Alfred Molina who worked with each other on Spider-Man 2.

Reunites Mike Judge and Toby Huss who worked together on the animated series King of the Hill (1997).

Bill Burr noted in an interview how convincingly angry Hugh Jackman looked in one particular scene that it he instantly thought he was with Wolverine and initially felt genuine fear. Murphy can be seen dropping his notebook on the ground in response, which wasn't planned in the original script. This candid reaction was left in the final cut.
