Welcome to the big list of movie plot holes and continuity errors! I’ll continue to add more as time goes on.
In Rocky IV, when Rocky leaves to fight Ivan Drago in Russia, his son is eight years old. However, in Rocky V (the next movie, in which he returns from Russia), his son is in his early teens. Maybe it was just a very long fight?
In the first Terminator movie, Kyle Reese explains that only organic material can travel back in time and that the T-800 was able to travel back because it is covered in organic skin (he says this after the police quiz him on why he didn’t bring back any futuristic weapons with him). Firstly: Why didn’t he just wrap a weapon in some sort of organic material? Secondly, in Terminator 2, the T-1000 was able to travel back in time, even though it was made out of a material called “mimetic polyalloy”.
In the vast majority of Santa movies, the adults never believe in his existence. My question is: How can they maintain this level of scepticism when presents are continuously appearing under the Christmas tree? Surely, you’d pick up on the fact that you didn’t purchase the $600 bicycle that your son is riding around on? Surely, you’d realise it when your daughter opens a gift that you don’t remember buying?
If Buzz Aldrin didn’t believe that he was a toy, why did he instinctively freeze whenever humans were around? I mean, he did think that he was a Space Ranger, didn’t he?
In Star Wars, Luke Skywalker is kept hidden from his father, Darth Vader. Vader’s original name was Anakin Skywalker. If they were trying to hide him, why did they allow him to keep his father’s surname? Also, why would they hide him on his father’s home planet, of all places?
In the movie Signs (2002), it is discovered that the aliens are deathly allergic to water. If this is true, then why on earth are they invading a planet that has rain, snow, oceans and rivers? Also, doesn’t earth’s atmosphere contain water?
In Independence Day, nobody believes Randy Quaid when he says that was abducted by aliens. This is despite the fact that a huge alien mothership has arrived and a dozen 15-mile-wide spaceships are floating over earth.
Also; how on earth was Jeff Goldblum’s character able to create a computer virus that was compatible with the alien’s system? Not only that, but it took him very little time to do it! And via what interface was he able to connect to the alien ship? Did he find some kind of special Mac-to-Alien USB adapter lying around?!
Jurassic Park 2
In the movie Jurassic Park 2, all of the crew members on board the ship that was carrying T-Rex were found dead. How did they die when T-Rex was still stuck in the cargo hold? Also, how did he manage to kill some of the crew members that were inside the ship, without causing any damage? Did he lock himself back up after his killing spree?
I Am Legend
At the beginning of I Am Legend, we are told that all bridges leading in to Manhattan were destroyed in an effort to stop the spread of the virus. However, later on in the movie, Anna Montez and her son are able to drive into the city. How?
In the movie Waterworld, dirt is a prized commodity. In one scene, a man sells a tomato plant (in a pot, with dirt) for half of the price of what a similar amount of dirt would cost. Why did the dirt in the pot cost less? Also: If paper is such a prized possesion, why is everyone smoking cigarettes?
The Little Mermaid
In the Disney movie The Little Mermaid (1989), Ariel lets us know that she can read and write by signing a contract with the Sea Witch, Ursula. Later on, her voice is taken away and she is seemingly unable to communicate.
Why not communicate via writing?
Planet of the Apes (1968)
In the movie Planet of the Apes (1968), a team of astronauts end up crash landing on a “strange” unidentified planet. Despite your average astronaut’s knowledge of the moon, sun and stars, these particular astronauts were completely unaware of the fact that this “strange planet” was actually earth.
The Purge (2013)
In the movie The Purge (2013), an event called The Annual Purge takes place. During this event, all crime is legal and police stations are temporarily shut down. Despite the horrors that such an event inevitably brings, people decide to stay hidden away in their bunkers, instead of just leaving the country for a day. I mean, really, even the rich decided to stick around, even though they could have been lounging around in Barbados for a week!
In Home Alone, Kevin McCallister rides a sleigh down his stairs, before sliding out of his front door. However, if you look at the scene where he is preparing the sleigh, you’ll see that the door is not directly opposite the stairs. In reality, Kevin would have slid right into the wall that was opposite the stairs.
Where oh where did Edward Scissorhands get those blocks of ice from? I mean, really – The guy is making ice sculptures… in his attic… in Florida.
Not a movie, but an interesting plot hole / continuity error nonetheless:
In Episode 11, Season 3, Waylon Smithers tells Mr Burns that they should probably go because several bees are currently stinging him. All in all, he doesn’t seemed too concerned. However, in Episode 21, Season 7, Smithers tells Mr Burns that he has a bee allergy that can kill him.
World War Z
In World War Z, we find out that the zombies completely ignore humans that are suffering from a pre-existing illness. In fact – They act as though they don’t even exist. If this is the case, then how did nobody notice the fact that people inside hospital wards were being left untouched? There are thousands and thousands of hospitals and health clinics around the word – Yet not one person picked up on this?
In the movie Aliens, we get to witness a small continuity error. At the end of the movie Alien (1979), Ripley places her cat into a separate hypersleep chamber. However, at the beginning of the movie Aliens (1986), we can see that Ripley and her cat are sleeping in the same hypersleep chamber. Because Ripley was in a state of stasis the entire time, there would have been no way for the cat to get into her chamber. Unless, of course, she woke up for a sneaky smoke break?
In the movie Jurassic Park, John Hammond tells his visitors that they spared “no expense”. If that is the case, then why did they hire one programmer to develop over 2 million lines of code? Surely they had enough money to hire a few more? You have the funds to breed extinct dinosaurs, but you can’t properly staff your IT department? Come on now!
OK, so what do we know about Forrest Gump?
- He’s a Billionaire.
- He personally uncovered the Watergate scandal.
- He was an All American in Football.
- He garnered a lot of media attention when he ran across America several times.
Yet, for some strange reason, nobody at the bus stop recognizes him.
