Factual error: There are two Marines posted at Marine 1, the Presidential helicopter. Their pants are ridiculously long and not the image of Marines with well-fitted uniforms. Their position of attention is wrong, with the hands clenched and placed on their thighs as opposed to being fixed at the sides. Worse, when they saluted with their right hands were above the service cap brim, instead of the fingertips touching the bottom of the brim.
Factual error: Captain Carrillo is target shooting with a hand weapon. She empties the magazine, but she catches the magazine and hands it to her ranger partner instead of letting the empty magazine fall to the ground. As a trained military officer and training with special operators, catching an empty magazine is an extremely bad habit and practice, which is a big no-no. (00:40:23)
Character mistake: Issei meets with a journalist to tell her that he has decided to end his participation in the contest to win the estate. She hands him her business card, which he immediately puts in his pocket. This completely violates the Japanese traditional business card ritual, which includes looking carefully at the card (a sign of respect).

Other mistake: The scene in which Tayo's wife gets into her car to leave their home is filled with mistakes. First off, it seems to take her much too long for the short driveway to reach the curb. Then, when she is blocked by the perp's van, she rams one of the perps twice and then backs away. As she is backing away, the perp's body flies forward, smashing into the van. She then rams the van twice with great force, and yet her car has minimal damage, only to the corner of the car.
Deliberate mistake: Identical twins Beverly and Elliot have the exact same beauty mark on their faces, roughly on the smile line directly across from the right nostril. Identical twins don't share features like that.
Other mistake: The police are watching a bus traveling between Philadelphia and Pittsburgh. As part of the surveillance, they show a policeman in a car taking pictures. The lens cap is still on.
Deliberate mistake: When the news program is discussing Gyrich's assassination attempt on Xavier from the series finale of the original animated series, he's shown to have his classic look of auburn hair and sunglasses. However, when this scene occurred, Gyrich had black hair and was not wearing sunglasses. This was done deliberately to match the character design of the original series prior to the final 6 episodes, when Saban took over and redesigned much of the show's look.
Factual error: The Royal Navy sailors are shown with just 'HMS' on their cap tallies. This was only seen in the Second World War for security reasons. In peacetime, the tally bears the name of the ship or shore establishment to which the rating is assigned.
