Titanic may be one of the most popular movies of all time, but that doesn’t mean it’s free of errors. In fact, while watching the film, you can catch a myriad of mistakes that no one working on the film caught. For example, throughout the film, Rose’s beauty mark changes sides.

How about the fact that if you watch the part where Rose frees Jack in slow-motion, you can see that she visibly hits his wrist?! In the same scene, Jack’s suspenders disappear. In another scene, you can even see one of the videographer’s cameras in the reflection of a door. Chances are that the type of camera being used on the film wasn’t around in 1912.

Of course, there are a few not-as-noticeable mistakes. These include glass reappearing where the safety axe is being kept, fixed parts of the ship suddenly disappearing from one scene to another, and Jack’s hair magically slicking itself back in the third-class dancing scene. You’ll never look at the movie the same way again!
