G.I. Joe: The Rise of Cobra (2009) - 18 mistakes

Factual error: Towards the end of the movie, the G.I. Joes head for the north pole to rescue Duke. In several of the scenes outside the base you can see mountains in the background but there are no mountains anywhere near the north pole - it is just ice.

Factual error: In the underwater scene when Rex blows up the ice pack, ice appears to be denser than water in this situation. The ice sinks when it's blown up, and even if there were pieces of metal on top of the ice, it shouldn't. Some pieces the size of a five-story building have no metal and still sink.

Deliberate "mistake": After being arrested, Breaker, who is Northern African, a region where French is the second if not first native language and speaks with a French accent throughout the movie, pleads with the French authorities in English.

Continuity: At the end of the Hummer chase through Paris the Hummer gets hit by a train on its right side, hitting the front right bumper. However when the Hummer finally lands, it is the front left bumper that has the impact damage, while the front right bumper is barely touched.

Continuity: During the chase in Paris, Storm Shadow is wearing a suit. However, in the helicopter right before his flashback, he is wearing his combat outfit. When the helicopter lands, he's back in the suit.

Continuity: Throughout the movie, Heavy Duty has an earring in his left ear. However, during the underwater fight scene, it is in his right ear.

Continuity: When Duke suited up in the van before the car chase in Paris, the Gatling gun was on his right arm, while the rockets were on his left. During the chase, right after they determined the target was the Eiffel Tower, Duke raised his left arm to fire the Gatling gun. Then a few moments later, Duke again raised his left arm to fire a rocket.

Continuity: After the Hummer crashes into the train during the chase in Paris, Ana crawls out of the wreck. The right side of her face is covered in streaks of blood. Seconds later, as she runs into the balloon guy, her face is spotless. The blood returns when Ana enters the glass elevator.

Visible crew/equipment: After Ana's husband has finished weaponizing the warheads in his civilian lab, Ana kisses him. The reflection of a boom mic is visible on the right lens of her glasses.

Factual error: During the chase scene through Paris, they start by driving through the Arc de Triomphe which is North West from Central Paris. Then the next scene the chase takes us by Notre Dame, where it is on the other side of town, North East. The Eiffel tower is on the west side of town. So, started at the North West, drove to North East of town, then drove back to West near the Eiffel. They could have just driven south of Arc De Triomphe and be there in something like 10 minutes.

Factual error: A few errors aside from Duke's change in rank, is that Ripcord is Enlisted. Even special forces Enlisted do not fly jets. Also, I understand that special forces are allowed to grow facial hair and keep long hair as part of blending in during operations, but Duke has a somewhat regulation hair cut and a manicured goatee. In his formal dress uniform, he would not be allowed to keep that little chin stubble.

Continuity: At the very beginning, as Ana is running away with the Nano warheads with Duke following, she is first holding the case in her right hand. Cut to a shot in front of her and the case is now in her left hand. It is back in her right hand in the next shot.

Factual error: There are no buildings in Virgina across the Potomac that overlook the Lincoln Memorial and National Mall from the angle and height depicted in the rooftop scene.

Continuity: When Ana returns home to her husband, they converse outside the house. He asks her how it was in Monte Carlo. As he asks her this, she is entering the front door and he is about 8 feet behind, following her. The next shot shows them both in the house, and they are very close together when she answers that she didn't get what she want.

Revealing: During the four-year flashback scene in East Africa, after the building is bombed, two helicopters fly to the right of the building. However, because they are CGI, the telltale whirl (or any movement) the blades should have made in the smoke isn't there.

Continuity: You can see the scar on Duke's cheek changes size throughout the movie. Compare the scar at the beginning of the film and the end. Much longer at the start, but at the end it is really small.

Factual error: In the great fight between the smaller subs, one of the Joe's small subs is hit and a crew-member is seen being blown out of his cockpit due to the impact. He screams, probably in agony. Oddly enough, he manages to do so under water. The funny part is that we are able to hear it.

Revealing: The clarity of the water in the Arctic scenes would not allow anyone to see the underground base from as far away as it was seen throughout various points in the movie.
