Titanic’s plot revolves around members of different social classes falling for each other. Rose and her mother, Ruth DeWitt Bukater (played by actress Frances Fisher), belong to a privileged stratum, so they are supposed to know the etiquette protocols very well. In fact, on several occasions, Mrs. Ruth reminds others to comply with them. That’s why it seems contradictory that in several parts of the film, she wears gloves to snack when the rules of etiquette forbid this: she should take them off when entering any room where food is offered.

Like the guardrails and the bow, the smokestack of the boat also seems to take on a life of its own. At the beginning of the film, the shape of the smokestack is different from what we see as the ship begins to sink. Remembering and preserving the set’s exact details must have been very complicated and cost a fortune, which is why that might have happened.

The ship’s officers wrongfully arrest Jack, and Rose rushes to his aid. But producers didn’t notice that a pillow appeared out of nowhere between scenes in the room. Did someone decide to take a quick nap?

Jack and Rose are stranded in the middle of the freezing Atlantic Ocean, where they both struggle to survive while waiting to be rescued. At the beginning of these scenes, both support each other, and because of the cold temperature, Jack gets what’s come to be known as a snotsicle. But a while later, the ice has melted when Rose tries to wake him up because help has arrived.

In 1997, when the film was shot, technology was not as advanced as today, and filming a scene required several cameramen following the actors from different angles. One of them can be seen in the reflection of the glass of one of the doors of Titanic. Undoubtedly, this error is hard to spot and edit without today’s apps.

Another wardrobe oversight is Cal Hockley (played by Billy Zane). This character, due to his jealousy, ruffles Jack’s feathers, referring to his poverty and emphasizing his ordinary manner of dress. But something that causes doubts in this scene is to see him with a dress suit and shoes, but without socks. This is a must-have accessory in formal attire, and even more so for the era on which the film was based.

We know that the movie’s filming lasted several months, so Kate Winslet’s nails obviously grew several times. However, for her character Rose, it was barely a couple of days. In some scenes, we can see that her nails look short, and the length changes drastically from one scene to the next.

When Jack tries to dissuade Rose from jumping into the icy waters of the Atlantic, he mentions ice fishing on Lake Wissota. The small detail is that the lake in question is artificial and was not created until 1917, while the Titanic sank in 1912. Something similar is true of the Santa Monica roller coaster that Jack promises to take Rose on. In reality, it was not built until 1916.

As we will find out later, the film set had quite a few logistical and design oversights. An example of that is how the bow changes. It definitely doesn’t look quite the same when Leonardo DiCaprio’s character is excitedly watching the dolphins jump, as it does in Jack and Rose’s iconic romantic moment.

Another curious continuity error is Jack’s hairstyle in one of the scenes in third class. After his charming dance with little Cora, Jack returns to the table, where Rose is waiting for him with his hair disheveled. However, we can see how in the next instant his hair is perfect and even has several layers of styling gel. Many of us would like his power to style our hair in seconds.

Astrophysicist Neil deGrasse Tyson commented on several errors in the film. For example, they did not consider the date, the course of the trip, and the position of the stars as they were seen in the sky that night. The film shows Rose and Jack on a clear, moonless night; according to the expert, this is incorrect.

The famous discord drawing had another major continuity error. Cal, Rose’s fiancé, discovers the picture in a brown folder. When he picks it up, he is enraged and wants to tear it up right then and there. The funny thing is that in the next shot, the folder is gone, and we see the crumpled sheet of paper in Cal’s hand.

One mistake that no one noticed was Rose DeWitt Bukater’s (played by actress Kate Winslet) mole. When the young woman was about to board the boat, her mole was on the left side of her face; however, several shots later, it was on the opposite side.

In her attempt to free Jack, Rose runs in search of an object that could be useful to save him. She manages to see an axe inside an emergency glass on the wall of one of the corridors. An interesting fact is that the glass is magically reconstructed after it’s broken to reach the axe.

Something really interesting about this film is that, after the ship suddenly hit the iceberg, it began to sink from the bow; consequently, the stern of the ship was gradually raised, that is, a strong inclination was created from the front that originated the rise of the rear.

According to the law of gravity, every object should always fall in the direction of the body with the strongest attraction, in this case, the Earth. But in the first image, the ship’s ropes seem to tilt parallel to the Earth. Although later on, we suppose that the producers were more attentive and corrected this mistake.

Scenes later, Rose is driven by impulse and is about to make a difficult decision. Luckily, Jack appears to make her reconsider. Now, there is an important detail in this scene: depending on the camera angle, Rose’s hand is either holding the train of her dress or not.
