When you watch a film, you're expected to suspend your sense of disbelief. However, the worst continuity errors in famous movies demand that you completely disregard your critical eye, or risk ruining the entire film. As sitcom continuity issues reveal, continuity errors in movies and TV happen all the time, and are usually the result of a hastily cut scene or a dab of awkward CGI.
In the case of terrible films like The Room or Troll 2, viewers expect continuity problems to be a part of the experience. However, as soon as you notice a continuity problem in a major film, it's hard not to feel disheartened. Unlike historical inaccuracies — which studios can cover up with eye candy like Ben Affleck and Josh Hartnett — continuity errors in a film put their issues front and center. Viewers are forced to overlook improbable circumstances and irrational characters, as major films with continuity issues pull people out of the fantasy and back to their futon and leftover takeout.
Film continuity issues appear in movies of all genres; major motion pictures, Hollywood classics, and cult hits all run the risk of continuity problems. Once you notice these continuity mistakes in major films, you start to wonder what all the studio money goes towards.
Before anyone proposed the idea of a self-driving car, Commando introduced the concept of a self-repairing car, though the invention was probably not intentional. In a moment made for the governator, Arnold Schwarzenegger pushes a beat-up Porsche into an upright position that reveals the vehicle's damaged side door; it's bad enough that the actor has to hop over the door to get in the driver's seat. Yet when it drives off, the car shows no dents, scrapes, or even a fleck of bird droppings. Even Pimp My Ride never lied this overtly.
The Wizard of Oz is one of the earliest examples of Technicolor in film, and also showcases one of the first continuity errors. When she first meets the Scarecrow, Dorothy has long pigtails that cover her chest, yet throughout their initial encounter, her pigtail length fluctuates, and her hair only comes to her shoulders at some points. Thank God the Scarecrow lacks a brain at this point, or else he'd see right through this misstep.
Terminator 2 is a film about time-traveling robot androids made of liquid metal, so it doesn't really care about coming off as believeable. In hot pursuit of the heroes, the Terminator Model T1000 hijacks a helicopter by headbutting the windshield and phasing through the gaping hole. Seconds after doing so, the helicopter reappears with its windshield fully intact, and you are reminded that you're watching the former governor of California run around with some terrible redeye.
Tarantino thinks that non-linear plot sequences permit plot holes, but a single bullet hole is all it takes for the illusion of "divine intervention" to come crashing down. After a gunman opens fire mere feet from contract killers Vincent Vega and Jules Winnfield, the only evidence of the gunfire is the bullet holes in the wall. Jules considers the incident a miracle, but anyone paying attention a few minutes before saw those holes already existed in the wall right next to Jules. So much for movie magic.
