Revealing mistake: In the scene where Shen is seen walking down the road as he tries to hitch a lift, you can see all the cars are driving on the right side of the road. However, in some background shots you can see the traffic moving on the left side of the road as it is supposed to in New Zealand where the film is shot.
Plot hole: When Farley is preparing to rescue Simon by towing him up with the rope attached to his van, he drops his "cigarette" into his crotch, causing him to floor the gas pedal. His back wheels begin to spin. This is impossible because the vehicle is still in Park. There is even a camera shot of the "PRNDL" proving this. I guess this goof is employed by the filmmaker to increase the dramatic effect of him subsequently slamming the Dodge into drive a second later and careening through the fence. (01:07:35)
Factual error: The slave ship the pirates overtake in the beginning is flying the tricolor flag of modern France, which was not adopted until the revolution in 1789. Blackbeard is set in 1717.
Factual error: In an interview before his first launch attempt, Charles explains that his flight plan is to make exactly one orbit of Earth, returning from orbit directly to the launch point, his farm in Texas. Launching from that latitude would necessarily incline the orbital plane to the equator, and Earth would rotate beneath the spacecraft's groundtrack during the roughly hour and a half period of the orbit. The craft would then land, not at the farm, but several hundred miles to the west.
Visible crew/equipment: When Dieter steals the rifles from the hut and approaches the other prisoners before their attack on the kitchen, a crew member (wearing a cap) can be seen moving from the right of the screen to the left with a camera or some other equipment. (01:19:35)
Continuity mistake: When Yankee goes into his bedroom after losing the baseball game in the sandlot, he tears a hand-drawn picture of himself, Babe Ruth and his dad off the wall. The pieces of the picture fall on the bedroom floor. A few shots later the pieces are missing. Yankee was the only one in the room, and he didn't move them. Plus the window is closed, so it couldn't have been wind.
Plot hole: The Death Note that Misa brings to L headquarters is supposed to be fake, but when Light touches it he can see the Shinigami Ryuk.
Suggested correction: Light saw Ryuk after he tried writing a name down in the piece of the notebook hidden in his watch. Since he touched that piece, it makes perfect sense he would see Ryuk as that piece was originally part of Ryuk's death note and wasn't swapped by L.
Factual error: When the Empress is dressing for the Chrysanthemum festival, bobby pins and hair pins are visible in her hair, not made available until the 20th century.
Factual error: Jerry says that Flynn argued with Stephen Hawking regarding the thesis of Hawking's book when Flynn was only nine years old. However, Flynn celebrates his 32nd birthday in the movie in 2006, meaning he'd have been 9 in 1983 and 1984, while Hawking's first book, A Brief History of Time, wasn't published until 1988.
Audio problem: When Neale arrives at the radio station and finds the bankrupt sign on the door, emergency sirens can be heard wailing in the background. The shot changes to a different angle and the sirens abruptly stop. When the shot reverts to the original angle the sirens can be heard again. (01:07:15)
Revealing mistake: The infant baby was computer animated in every scene in which the face appeared. Even the feet were obviously touched up by computer in the hallway scene. The lighting isn't quite right, the skin texture isn't quite right, and the child's face is just too animated.
Continuity mistake: When Joe meets the President he is wearing orange Crocs, but when the President grabs his head he is wearing black flip flops.
Continuity mistake: After Stark fights with the Wakandians his armour is damaged, but while he is drinking on the ship the damage is repaired, then the suit is broken back again.
Factual error: Sharpe follows a wagonload of powder kegs into the Western Gatehouse, then down a corridor lit with torches, to the end of the corridor where Indians were tying together quickmatch, once again by torchlight. With the propensity for powder kegs to leak, even an Indian subadar would use closed lanterns.
Continuity mistake: During the bus scenes near the beginning (that take place after the paintball sequence), the backgrounds looking out the windows of the bus change in the shots. Some of the scenery outside is city, back to open land, and back to city.
