At the cabin in the woods, Clay pushes down his portable radio's antenna twice.

The helicopter flown by the FBI into the Salient compound (when seen from inside where Wade is standing) is black in color. When the agents walk out and towards Wade the same helicopter is now silver-colored.

The number of keys stuck down on Clay's typewriter changes between shots.

At about 44 minutes, a call on the police radio says, "Subject has crashed about mile marker 34." This was on an unmaintained service road. These are dirt or gravel roads with no markers.

Once again Hollywood believes that Oxygen is explosive and in this film brings down a whole building. Oxygen supports combustion but itself is neither combustible nor explosive.

It's not oxygen, it's liquid nitrogen. The label is clearly displayed in two different shots.

While there is a reference to 'heating' liquid nitrogen. It should be known that pure Nitrogren (N2) in any state is one of the most stable chemicals on the planet - second to only noble gasses. Heating it may cause structural failure in the container holding it, but there is zero chance of combustion or explosion beyond the venting of the over-pressurized contents.

When VP Kirby is on the phone from the Oval Office with Jennings, there is no way that call would not have been monitored in real time and recorded.

When President Trumbull is in the hospital, the Vice-President is sworn-in as President by a judge. Since the President is incapacitated by his injuries it would not be necessary for him to be sworn-in because he automatically assumes the role of president through the terms of the 25th Amendment.

At six foot tall, or nearly 183cm, Clay Banning would have been at least six inches taller and substantially larger than the average tunnel rat in Vietnam. It's exceedingly unlikely he would have served in such a role as he would not have been able to physically traverse the small, narrow tunnels that the Viet Cong used.

In the truck driving scene when Banning hits the tree with the trailer and it falls over disconnecting from the truck the truck should've flipped too. The locking jaws and 5th wheel plate are designed to keep and truck and trailer together so hitting a tree would cause both to flip.

When Mike is driving the semi down the dirt road, the spray from the camera vehicle is obvious in the frontal shots. The spotlight shots from the helicopter show the weather is clear.

When refilling their vehicle at the West Virginian gas station, a European road sign (white arrow in a blue circle) is visible in the background.

Peugeot cars can be seen driving around Pennsylvanian streets; the car is not sold in the US.

At around 79 minutes, Banning is going to Trumbull's hospital in Washington, DC. The background has mountains. DC is not close enough to the Appalachians for them to be seen in any form.

Why would the masterminds pick Mike Banning to frame for the assassination attempt on the President? The government knows he successfully saved U.S. Presidents in the past two terrorism crises.

An aide tells the Vice-President that the transfer of power back to a president has never happened in U.S. history. This is incorrect: On July 13, 1985 Ronald Reagan underwent colon cancer surgery while under anesthesia, so Vice-President George Bush discharged the powers and duties of the presidency during his incapacity, serving as acting president until later that day, when Reagan reclaimed his authority. President George W. Bush underwent a colonoscopy procedure on June 29, 2002, and again on July 21, 2007. Vice-President Dick Cheney temporarily became Acting President on both occasions, then power was transferred back to Bush. Additionally on November 19, 2021, President Biden had a colonoscopy and transferred acting president power to Vice-President Harris for 85 minutes.
