A 1965 Cadillac Hearse is at Lee Harvey Oswald's funeral.
A title card at the end of the movie says that Agent Forrest Sorrels died in 1993, at age 82. He was actually 92. During his testimony before the Warren Commission in 1964, he said he was 63, making his birth year 1901. He began his 47-year government career in 1922, when he was 21.
The Kodak logo on the 16mm film box was not used until at least 1971.
Throughout the film, Secret Service agents carry M16A1 rifles, with a birdcage flash hider and forward assist. That model was not available in 1963. At the time, the Secret Service used the original-model M16, with a three-prong flash suppressor and no forward assist.
When the agents carry President Kennedy's coffin aboard Air Force One, they saw part of the door away in order to get the coffin inside. According to Secret Service Agent Clint Hill, they had to remove the coffin's handles to get it on the plane.
The Zapruder film is mentioned as being a 'new' format. The film depicted is Kodak's standard 8mm, introduced in 1932. A new 'Super 8' format was introduced in 1965. Kodak's Kodachrome film had processing included in the price, so that the film would only be processed in a Kodak laboratory. Other film processing laboratories usually wouldn't stock the propriety chemicals used to develop Kodachrome film because customers wouldn't be expected to pay for processing twice.
In the film, the Presidential Limousine has two inboard red headlights. The limo did not have those lights until after it was rebuilt in 1964.
The O'Neal's ambulance in the ambulance entrance is a 1964 Rambler Classic 770 wagon. The actual vehicle, which was also used when Lee Oswald was shot two days later, was a 1962 Ford Galaxie wagon.
Marilyn Sitzman stands next to the concrete pedestal Zarpuder is standing on. In reality she stood on it with him to hold on to him, at his request, because he suffered from vertigo.
During the resuscitation of Oswald, Nurse Nelson uses a cardiology stethoscope in several shots. Cardiology stethoscopes did not exist in 1963.
The telephone handset that Dr. Carrico uses in the residents' lounge has a modern plug.
The Tektronix scope used in the operating room to monitor the president's heartbeat is too modern for the early 60's.
The scene of Oswald's resuscitation is historically inaccurate. The movie suggests that he died in the emergency department. The shot of Oswald being pronounced dead shows a simple resuscitation mask being removed from his face with no breathing tube. According to medical records, Oswald arrived in the emergency department with an endotracheal tube in place, placed into the trachea through the mouth. The same records state that Oswald died in the operating room, after receiving several different life-saving drugs and massive amounts of blood and fluid. This was not shown but was probably omitted to save time.
In the film, Kennedy's body is wheeled into the hospital with the head and upper body exposed. Secret Service agent Clint Hill draped his suit coat over Kennedy's body before it was moved to prevent anyone from seeing the President's wounds.
Some of the award ribbons on the uniforms of the Air Force officers helping to load the casket onto Air Force One are non-existent in the real Air Force. In addition, of the ribbons on their uniforms that do actually exist, several are not worn in the correct order of precedence.
When nurse Nelson begins treating Oswald, blood smudges are on her left cheek. In subsequent shots the smudges are gone.
The 1964 Cadillac hearse used in the movie does not have chrome crosses on both sides of the back, like the real-life hearse.
The aft boarding ramp, which Kennedy's coffin was carried into the plane was clearly marked as belonging to Eastern Airlines. The one in the movie has an unrecognizable logo.
The interior of Air Force One is incorrect. The set used in the movie depicts a scheme that wasn't adopted until the mid-1970's after the 747 was introduced. In addition, the interior was not done in brown, it was done in various shades of blue and white.
Love Field is shown as being surrounded by trees and brush, but in reality the location where Air Force One was parked was across the street from a parking lot and a hangar and cargo buildings stood to the south.
There is no tent over Oswald's grave.
When Zapruder is filming the assassination, he is in the correct spot but he is alone on the pedestal when in fact his secretary was standing behind him and holding him steady.
This one is more of a murky detail depending on how you sway but when the body of JFK is being wheeled into Parkland, the top and side of his head can clearly be seen to be "fully intact" instead of blown out with brain matter falling out as "some" autopsy photos show.
