Alexander. In the movie’s opening scene, Ptolemy I Soter, an elderly character, discusses Alexander while the lighthouse of Alexandria operates in the background. However, historically, the lighthouse was not completed until after Ptolemy I’s death, during the reign of his son, Ptolemy II Philadelphus.

Frida. In the movie’s opening scene, a group of men are shown carrying a bedridden Frida. While lying down, she looks up at a large mirror above her head, and her dangling earrings expose a behind-the-scenes secret. However, in this particular shot, Salma Hayek is depicted standing up, whereas earlier, she was shown lying down.

The Other Boleyn Girl. In the movie, Natalie Portman’s character, Anne Boleyn, is shown wearing various French headdresses popular in 16th-century England, replacing traditional English headdresses. However, in one scene, the costume designers made an error by not combing back the heroine’s hair, which contradicts the rules of wearing French headdresses. Although most viewers may have missed the mistake, fashion historians were not pleased.

Twilight. Vampires in the Twilight universe only get scars when other vampires bite them. That’s why tattooing vampires seems impossible since their skin will heal from any needle that can penetrate it.

Marie Antoinette. Upon closer examination, it becomes apparent that the queen’s son is wearing hair extensions.

The most famous scar in cinema is undoubtedly Harry Potter’s, and not only because of its lightning bolt shape, but also because it was left by “He-Who-Must-Not-Be-Named”. However, in Harry Potter and the Sorcerer’s Stone, when Dumbledore leaves Harry with a family of Muggles (non-magical humans), we see that he does not have the mark on his forehead (00:03:42). In the second shot, it magically appears (00:03:49).

Back to the Future. During his parents’ prom in 1955, the main character performs with a Gibson ES-345 guitar, which was created in 1958. Even time travel cannot explain how Marty acquired this guitar 3 years before its release.

Jurassic Park. The T-Rex comes out of a heavily forested area, eats the goat, tears down the fence, and suddenly all that land disappears, replaced by a large dam that Alan Grant can rappel down. Huge budget film, massively famous director. I still wonder how they got away with this 30 years later.

Pearl Harbor. While at dinner, Kate Beckinsale’s character removes her handkerchief and leaves it behind. However, when she departs from the table, no handkerchief is visible. After a few seconds, the handkerchief miraculously appears on the table.

The fourth Transformers movie has some military guys looking at screens and some of the screens still have green screens that were never replaced.

Pulp Fiction. A watch displays a specific time during Christopher Walken’s character’s recollection. However, when the camera zooms in on the watch’s face, it becomes apparent that the hands of the watch are positioned in a completely different manner.

Avengers: Endgame is one of the most successful movies of all time. In the scene where some kids approached Hulk to take a picture, we can see that the pancake is cut in the middle (00:38:00). Thirty-eight seconds later, the two halves are joined together. Could it have been Doctor Strange?

Once Upon a Time in Hollywood. The majority of the characters in the movie wear anti-reflective lenses, which were not commonly used until the 1980s, and the quality of the coatings was subpar at the time. As a result, it would have been impossible for Sharon Tate to have worn glasses with this type of coating in 1969.

Ocean’s Eleven. Brad Pitt is renowned for his insatiable appetite; nonetheless, it would have been improbable for the actor to consume two distinct dishes during a brief scene, no matter how voracious his appetite may be.

The Matrix. The camera is visible in the reflection of the doorknob in the scene. Despite the filmmakers’ attempts to conceal it, such as covering it with Morpheus’ jacket, attentive viewers noticed the mistake.

The Graduate. Per the film’s storyline, the protagonist travels to Berkeley, a city on the eastern side of the San Francisco Bay. However, the viewers can observe Dustin Hoffman’s character driving on the bridge’s upper deck, which is in the opposite direction.

Moulin Rouge! During a particular scene, the thin straps of Nicole Kidman’s dress are briefly replaced by wider straps for a few seconds.

It took 20 years for us, at least, to discover that Johnny Tran, from the first installment of The Fast and Furious saga, was the fastest of them all. After one hour twelve minutes and fifty-six seconds (1:12:56) of the movie, we see Johnny wearing a black shirt. Three seconds later, he is in a sleeveless T-shirt.

In Pretty Woman, Vivian, the character played by Julia Roberts, is enjoying a delicious croissant during the breakfast scene (00:32:21), but right after admitting that she only finished high school (00:32:38), the croissant turns into a pancake.

Notting Hill. In a scene where the main character bumps into Julia Roberts’ character, she looks up, and the reflection of the entire film crew is visible on her sunglasses.

Parts of the green screen toward the end of the first Charlie’s Angels movie were not properly rendered, so there are a few quick shots of Sam Rockwell “piloting” a helicopter against a neon green backdrop.

In Ace Ventura: When Nature Calls, when Ace is confronting the bad guy near the end. The bad guy is sitting at a chess table by himself. Halfway through the scene, all the chess pieces vanish.

Harrison Ford is standing in front of fake bookshelves in Indiana Jones and the Last Crusade. It may be a minor thing, but it is obvious.

In Home Alone, when Kevin is eating his macaroni and cheese meal, the clock rings 9, then cuts to Kevin blowing out the candles. When the bandits come in, there’s a completely different microwavable dinner on the table.

In Titanic, inside the ship, they splash around in the ocean water like its warm bathwater yet die of hypothermia in minutes outside the boat.

Titanic. The water in the ocean is typically murky due to the large quantity of organic waste present. However, the film depicts the water as being crystal clear.

Spotlight. Throughout the scene where the journalist played by Rachel McAdams interviews the crime victim, they are seen taking notes, but upon inspection of their notebook, it is revealed that there is not a single word written down.
