The 30 Biggest Set Blunders in Movie and TV History

There's been a lot of confusion about the time period that Riverdale takes places in—mostly because the old time-y set design clashes with the characters' modern day technology. This hospital scene in particular had people scratching their heads because the nurses are wearing candy striper uniforms.

When it comes to newborn babies in movies, dolls are often used. But it takes a lot of strategic angling and pre-recorded crying noises to make a fake baby look real—something that didn't happen in American Sniper. It's obvious from the minute Bradley Cooper picks the doll up, despite his attempt to sneakily move the baby's hand with his finger to make it seem alive.

From one cut to another, it seems that many random props—and even people—can appear out of nowhere. Around minute 2:18, there's a wide shot of Mark Wahlberg's character running to hide behind a wall. It then cuts to a close up of him at the wall and there is suddenly another person beside him.

In a fight scene where Catwoman has joined forces with Batman in The Dark Knight Rises, one extra can be seen throwing himself to the ground. No one is around him at the time he falls. Guess the extra went a little...extra here.

Plot holes in storylines are sometimes inevitable after so many seasons, as is the case for GOT. In the season six premiere of Game of Thrones, it was revealed that Melisandre's necklace has youthful powers—when she took the necklace off, she became an old hag. But back in season four, Melisandre wasn't wearing the necklace and she looked young. So how exactly does this necklace work?

Yes, blunders can happen in animated films too. In the scene when Rapunzel is comforting Eugene after he's been stabbed, there is one noticeable error. Eugene's hands are shackled, but as he goes to brush the hair out of Rapunzel's face, the restrains suddenly disappear. It would make sense that they slide down his arms as he lifted them, except the next shot shows his arms in a similar position—but with the shackles around his wrists.

Angles are everything—especially when it comes to the biggest scene in this movie. As a plane is about to crash on the highway, the policeman talking to Nicholas Cage's character steps backward in fear. But, when Cage turns around, the plane comes from his right side. So what did the police officer see behind Cage?

The infamous pizza-on-the-roof scene from Breaking Bad brought a few inconsistencies: The pizza was left on the roof for the entire episode—but its placement was different in almost every shot. At one point, it even gained some extra pepperonis on top.

When Barney must decide to give up suits or women, he dramatically decides via song. All the extras are dressed from head to toe in nice suits—except one extra who forgot to bring a pair of dress shoes. You'll find her on the right side, third person back, at minute 1:50. She's only there for a few seconds before she runs off screen.

If you pay attention carefully, you'll notice that the numbers on John Connor's getaway plane are different when he's in the air from when he first boards. Before take-off, the identifying number is N3035C, and when he's in the air, it's N3413F.

In the final scene of the first Pirates of the Caribbean movie, Captain Jack Sparrow gives a speech after taking control of the Black Pearl. As the ship's crew starts moving, there is suddenly a man in a cowboy hat, and we really don't think they had those in the 1700s. Pause the video at 1:36 and you'll see him to the left of Sparrow's head.

There's always the possibility of an extra getting hurt on set, and unfortunately that's what happened in The Last Samurai. Tom Cruise's character rides in on a horse, and as he's stepping off, the horse kicks an extra right in the stomach.

While Harry Potter and Draco Malfoy are duking it out with their wands in the second film, Harry knocks Draco to the ground. On the lefthand side a cameraman can be spotted at 12 seconds.

Pippin and Merry's hands are tied—literally and figuratively—when they are about the become dinner. Luckily, they are saved, and begin to crawl away. Just as Pippin is about to be trampled by a horse, he flips on his back and his hands have magically become free of the rope.

Crew members aren't always the best at ducking out of shots—but this one had a very specific job that made it almost impossible to do so. The story goes that the red dress Lois is holding had to be kept in a bucket of water and quickly passed off to her for the scene. If you watch carefully, you can see the bucket the dress is pulled out of and the cameraman.

One of Mel Gibson's biggest movies had quite a few noticeable flaws—many involving modern day items. In one instance, a crew member in a black baseball cap is seen walking through the shot. Later on in a war scene, the two sides charge at each other and a white car is visible in the background.

Quinten Tarantino made one very noticeable mistake in this scene from Pulp Fiction—just look at the wall behind John Travolta and Samuel L. Jackson. Before shots are even fired in their direction, there are somehow already bullet holes in the walls.

Sometimes directors realize logistical errors after a show has already aired. In the first few episodes of Friends, Joey and Chandler live in apartment 4 and Monica and Rachel in apartment 5. But since the girls have a balcony that looks down into Ugly Naked Guy's apartment, it wouldn't make sense for them to live on the ground floor. Their apartment numbers were switched to 19 and 20, respectively, to make it more practical.

As Hulk Hogan's character rides his motorcycle along the ocean, there is a moment (at 16 seconds) when we see a person throw a dog into the water. It doesn't seem like it was intended to be in the shot, but it still made it into the final version of the movie.

In the 1993 original Jurassic Park, a velociraptor enters the kitchen searching for the kids. When it first opens the door, a human hand touches the tail for a second, as if it were supporting the velociraptor. It's likely that a crew member was steadying the prop dinosaur. Even if it was just for a second (at minute 1:09), it's very hard to unsee now.

Verne Brown, the youngest boy standing next to the dog, can be see subtly motioning to Marty and Jennifer and pointing to his crotch. It's unknown as to whether or not this was something that was overlooked in editing, or if it was some sort of hidden sign.

Poor set design can be the reason for a TV show blunder. In the first episode of The Fresh Prince of Bel Air, Will staples a poster to a very wobbly wall. Watch as the set shakes even though he barely touches it.

During an intense car chase, John Matrix’s yellow Porsche gets extremely beat up. But as he drives away after the incident, the car looks like it's been completely untouched.

At the end of the movie, one of the extras had a wardrobe malfunction. As Scott's dad gets up to congratulate his son, an extra can be seen in the background with his pants noticeably unzipped.

At the end of the movie, Data tells a reporter that the scariest thing about his trip was fighting off the giant octopus—but that scene was deleted from the version released in theaters. The octopus scene was later added into the Disney channel version of the movie because several other not-safe-for-kids scenes were taken out.

Every now and then a crew member will make an accidental appearance in a film—and it's blatantly obvious in Raiders of the Lost Ark. A man in a modern T-shirt walks through the crowd behind Indiana Jones as he's drinking at the bar after Marion supposedly died. This was just one of the many editing errors in the film.

One of the most famous scenes from the movie takes place in a hedge maze that is supposedly located right behind the hotel. However, in the establishing shot of the hotel at the beginning of the film, there is no hedge maze—just a parking lot and mountains.

While chasing down Luke, Leia, and Han Solo in the first Star Wars movie, a group of Stormtroopers bust a door open by shooting it. The only problem is, the door doesn't open all the way, and one of the Stormtroopers bumps his head while walking through. The accident didn't go unnoticed by director George Lucas who added a "boink" noise to make the mistake seem like it was intentional.

Even influential film director Alfred Hitchcock missed small background blunders. The most noticeable in this spy thriller is when a little boy plugs his ear just moments before Eve shoots George. The extra obviously knew she would pull the trigger, and prepared himself in advance.

As Dorothy and the Scarecrow travel on the yellow brick road, they stop to pick apples—except the apple trees are alive. The animated trees throw their fruit at the Scarecrow, knocking him down. A wide shot reveals that Dorothy is not wearing her ruby slippers, but instead, a pair of black shoes. Pause the video at 1:04 to see the error.
