False constellations
Neil DeGrasse Tyson, a renowned astrophysicist, discovered this plot hole. After seeing the film, he noted that the constellations depicted in the film are not compatible with what the passengers of the Titanic would have seen in real life, given their position. He then provided Cameron with the right version before releasing the 3D version of the film to repair the error – though we doubt many people were aware of it in the first place.

Multiple CGI mistakes
Despite his desire to incorporate as many physical effects as possible, Cameron had to use CGI for some of the more intricate scenes in the film. This resulted in a slew of issues, ranging from unrealistic shadows to vanishing things that appear and disappear from the ship’s deck and pipes that change shape throughout the film. This is the risk of employing CGI in a film (particularly in the ’90s), but it’s nonetheless disappointing that things weren’t left on the editing room floor.
