Factual error: In 1999 when April is filming inside the research facility, you can see her video camera displaying Bluetooth, which wasn't available in cameras until 2002.
Factual error: During the Nick Fury chase scene that takes place in D.C., several black and white state highway 6 signs are visible. These signs are unique to Ohio. Route 6 goes straight through downtown Cleveland where the scene was filmed. Plus during other chase scenes several Cleveland landmarks are visible in the background. (00:28:30)
Factual error: The idea that humans only use 10% of their brain is a widely-circulated myth that has been debunked by neurological science many times over.
Factual error: What kind of small American town has an airport that has 6 jumbo jets sitting on the runway? I mean, I think Dallas is the closest airport in the region that would have 4 engine 747s at the ready. Topeka, Oklahoma city, etc. commercial airports could barely handle one 747, let alone 5-6.
Factual error: During the decompression the plastic water bottles crush. The opposite should happen, as a decrease in external pressure would cause the bottles to expand.
Factual error: In the Japanese prison camp, the Japanese flag shown is the post war flag consisting only of a red circle. (01:08:05)
Factual error: When they show Alex's partner in the hospital his heart rate is showing 35 on the monitor. His heart rate is not that low from the EKG pattern.
Factual error: Before the eruption, we see Mount Vesuvius with a crater. Mount Vesuvius did not have a crater prior to the eruption in AD 79. This can be seen in a fresco depicting Mount Vesuvius found in Pompeii.
Factual error: The movie depicted the use of obstetrical ultrasound. While ultrasound was first "perfected" in the late 1950s, it wasn't used in British hospitals until the 1970s and not in US hospitals until well into the 1970s, well past the setting of the movie in the 1960s.
Factual error: When Magneto enters RFK stadium, a groundskeeper is lining a baseball field. RFK stadium did not host baseball in 1973, as the Washington Senators had moved to Texas to become the Texas Rangers after the 1971 season. In 1973, the only team playing in RFK regularly was the Washington Redskins of the NFL. In addition, the Paris Peace Accords were signed in January of 1973; so there wouldn't be green grass inside the stadium, regardless of what sports were being played there.
Factual error: During the final fight, Liam Neeson jumps down an aisle to pick up the pistol that is hurled from the floor upwards in the air and shoots the villain in the head. The problem here is with physics. The plane was in radical descent moments before. The pilot eventually brings up the nose. At that moment, the gun and Liam Neeson himself would have been pinned to the floor.
Factual error: They find an old video camera from their dad, but that camera is already 10 years old. And the battery just works?
Factual error: Tammy hits a buck with her car, which has polished antlers. The next day her and her grandmother are in the woods, and they see another buck, whose antlers aren't fully developed, still in velvet. These two scenes would have to be several months apart for antlers to be that different.
Factual error: When the car goes to the bottom of the ocean after the chase, the water in it is raising as if leaking in, despite the fact that the door on Hiro's side is missing and the water should be rushing in. (00:50:15)
Suggested correction: I watched the scene and it looks like it's filling up the way it should. It's looks similar to the way a car fills up after being submerged with the windows open.
Not true, water is still filling up the car way too slow for an opening like this. The car should be filled up immediately.
You're wrong thinking it would fill up immediately. But even so, it fills up in about 10 seconds (even less if the shot of it filling up is meant to be a simultaneous shot and not continuous).
Factual error: Towards the end of the film, Spiderman takes his web and uses it to connect to the different power conduits that Electro blew open, ties them together, and power the city back up. Electricity uses several different wires, and crossing them would cause things to blow up or short out. What should have happened when Gwen threw the switch was another power failure, instead of the city's power being restored.
Factual error: When Vlad goes into the Master Vampire's lair a second time, a Golden Knee Tarantula can be seen. These types of spiders are native to the Chaco region of Argentina, South America. Not in Eastern Europe.
Factual error: In the rat revival scene, Dr. Terra Wade, an electrophysiologist, demands that the other scientist, Dr. Bell increase the current, going as high as 200 joules. However, current is measured in amperes (amps), joules is a unit of energy.
Factual error: The view from the aircraft Jane is flown home from France in shows the modified double engine pod of the 747 famously at Dunsfold Airfield, Surrey. Also a late livery grey RAF VC-10 parked in the distance. Also the engines of the plane she is in are upgrades and not right for the year it is supposed to be happening. (01:23:20)
Factual error: The corpse's head in the cafe changes position between shots. (00:34:00 - 00:35:00)
Factual error: At the diner scene at the Gimli Slider, there's an ashtray with a lit cigarette on the table. Manitoba has had a smoking ban in all enclosed public spaces for over a decade.
