As far as historical movies go, “Gladiator” isn’t the most accurate, but it’s still remembered as one of the best. During the re-enactment of the Battle of Carthage, a chariot hits a wall and flips over, revealing a gas canister hidden in the back to help the vehicle get up to speed for the movie.
The Romans had plenty of technological advancements, but pressurized gas wasn’t one of them. Unfortunately, resetting the entire action scene would have cost too much and taken too long, so they had to go with the shot that they got.
“Terminator 3: Rise of the Machines”: I Think Those Numbers Changed
While running for their lives and trying to stop the machines from taking over, John Connor and the rest of the cast have to take to the sky to try and stay one step ahead of the machines.
When they approach the plane on the ground, the plane's call number is clearly – as you can see from the picture – N3035C. However, once they're in the air, the plane's numbers change to N3413F. The reason for this is almost certainly difficulties with filming and renting planes, especially while flying.
“Commando”: The Magical Rebuilding Car
The 1985 movie “Commando” includes plenty of fun action scenes with our man Arnold, and one of those scenes is a long car chase sequence. One of the characters is driving a Porsche, and as you might expect from an eighties action movie that stars Arnold Schwarzenegger, the car is pretty beat up by the end of the scene.
In the next scene, however, the car has somehow been rebuilt and repaired. It's part of the charm of movies in the eighties, which were less about stellar filmmaking and more about making a movie that was simply a lot of fun.
“Jurassic Park”: Why Are You Speaking to That Video
Programmer turned thief Dennis Nedry, played by Wayne Knight, is the biggest reason Jurassic Park went from the most amazing theme park ever to a disaster. At one point, Nedry appears to be talking with an accomplice on his computer via a live feed, as we do pretty often today. However, a closer look reveals that he's actually watching a pre-recorded video and speaking back to it.
While it's clearly just a technical limitation the filmmakers had to work around, it's pretty obvious nowadays, and with increasing technical skills, it becomes more and more laughable every year.
“Twilight”: Bella, There's a Cameraman
“Twilight” is fun in its poor filmmaking, thanks in part to the barren expressions of lead star Kristen Stewart. The film itself is rife with errors, and one of the most noticeable mistakes is being able to see a cameraman in the curve of Bella's truck, such as you can see in the picture.
A mistake like this reminds the viewers that they're watching a movie and can take them out of the experience – breaking rule number one for most artists of any stripe, be it writers, directors, or musicians.
