No matter how much we enjoy movies, we can’t argue that even the most well-respected directors occasionally commit some pretty egregious errors. Many of the most well-known films have been stained by a degree of production flaws.

The stormtrooper hitting his head in Star Wars

One of the stormtroopers on the right of the screen hits his head on the door frame as a squad of stormtroopers approach a control room in Star Wars: Episode IV – A New Hope. They added a thump as he hit it on the DVD release.

 The eyes of Harry and his mom in Harry Potter and the Deathly Hallows

Several characters inform Harry that he “had his mother’s eyes” in the Harry Potter books and films, which is interesting. However, when we first saw Lily Potter as an infant in Harry Potter and the Deathly Hallows, it was clear that she had brown eyes that aren’t similar to Harry’s blue eyes.

The orange bike lights in Stranger Things.

The lights on the front of the boys’ bikes were bright white in other Stranger Things scenes, so it’s odd that they seemed orange during the daytime. The lights were most likely coated with an orange gel to mimic the color temperature of the professional lights used for manufacturing, or perhaps to dim the lights, according to Jalopnik. However, it’s possible that, like the show itself, it’ll remain a mystery.

The Osama Bin Laden reference in Breaking Bad.

One of Breaking Bad‘s main villains, Jack Welker, mentions Osama bin Laden’s death to his nephew, Todd, at one point. However, the show was set in 2007, and Osama bin Laden did not die until 2011.

In an interview with Slate, Vince Gilligan pointed out the error, saying, “‘I thought this show was in 2007, and it’s only been a year since then, but last week you mentioned the Osama bin Laden assassination,’ the writer said. ‘How can you make use of that?’ ‘Well, frankly, I don’t,’ I had to admit.”

The hydrofluoric acid was eating the tub in Breaking Bad.

One of the first gory scenes in Breaking Bad was when Walt and Jesse tried to dissolve a body in hydrofluoric acid in a bathtub, which resulted in a very messy situation. Mythbusters, on the other hand, demonstrated that this could never happen in real life.

The mention of ‘the octopus’ in The Goonies

Data says at the end of The Goonies that the scariest aspect was “the octopus,” which isn’t in the movie’s original version. For the theatrical release, the scene with the octopus was cut, but younger audiences reintroduced it for the Disney Channel version.

The shirt Tran’s wearing in The Fast and the Furious.

In the scene where Jesse and Tran race in The Fast and the Furious, there was a pretty glaring flaw. Tran was dressed in a jersey with sleeves in one shot and a crop top in the next. In this video, the contrast between 0:55 and 0:58 can be seen.

The name mixup in Supernatural.

In the first season of Supernatural, viewers found a significant error. Dean seems to refer to his brother as “Jared” in the episode “Provenance,” which is the actor’s name but not the character’s. In another scene, you can hear what seems to be an extra naming Dean “Jensen,” which is, like the character’s name, the actor’s name.

The Starbucks coffee cup in Game of Thrones

The internet blew up after viewers saw a Starbucks cup in the final season of Game of Thrones. “At first, I couldn’t believe it,” producer David Benioff told Japan’s Star Channel. “Then it was a shame, like, ‘Why did we not see this coffee cup in the middle of the shot?’.” The degree of humiliation they faced after it blew up on the internet was truly something.
