When Bush approaches Cheney to be his vice-president, the position of Christian Bale's hands, and what he holds in them, changes between shots (in one shot, Cheney is gesturing with empty hands and is then instantly seen holding a drink).
In the movie, all the characters including Cheney family members, pronounce the family name as "chain-y". The Cheney family has always pronounced their name as "cheen-y".
The film suggests that Dick Cheney got his start interning for Donald Rumsfeld first when in fact, he was an intern for Congressman William A. Steiger before joining Rumsfeld's staff.
The trend to wear the American flag on the lapel didn't happen until after 09/11/2001. Bush and Cheney wearing the American flag on their lapels during the 2000 campaign is incorrect.
In a scene with Cheney and President Gerald Ford in the Oval Office, behind Ford is a photo of former First Lady Pat Nixon. The First Lady at this time would have been Betty Ford.
When Cheney fires Rumsfeld over the phone, the office chair in which Rumsfeld is sitting is a modern mesh back design which wasn't available in 2006.
This is wrong, as the chair in question is a Herman Miller Aeron, which was introduced in 1994.
In the middle of the movie, the Cheneys are said to raise Golden Retrievers. The two dogs shown with them are Labrador Retrievers.
The secure conference room which is assigned to Dick Cheney in the CIA office would not be secure as it has exterior windows.
When Donald Rumsfeld is introduced, it is stated that Rumsfeld was an elite Navy Jet Pilot. In real-life, Rumsfeld never flew jet-engine aircraft during his service within the Navy. Most of aircraft that Rumsfeld flew there were propeller engine aircraft.
Camille James Harman is credited as playing "Mary Matlin". The character's surname is actually spelled "Matalin".
The scene in which the young Dick is weaving down the road is set in 1963. The road has yellow dashed paving markings, which were not used until 1970. In 1963, the dashes would have been white.
The train seen briefly in the beginning of the movie showed modern diesels that were 30 years too new for the time period.
In a scene set in 1973, Cheney can be seen lying in bed and talking to Rumsfeld on a non-Trimline telephone with a modular handset. Modular connectors were not available for telephones other than Trimlines until 1976 and weren't ubiquitous in the United States until the early-1980's.
In a scene set in the early 2000s, a man is wearing a Tampa Bay Buccaneers jersey with a Nike logo on its sleeves. Nike didn't take over the manufacturing of NFL jerseys until 2012.
During a party scene where Dick Cheney talk to with George H. W. Bush, it is seen that Dick Cheney is taller than George H. W. Bush. In the real life George H. W. Bush is far more taller than Dick Cheney.
