Everyone involved found filming Titanic to be extremely difficult, especially given all of the issues that arose on site, such as individuals falling seriously ill and Kate Winslet almost drowning.
James Cameron, the filmmaker, performed brilliantly on it in spite of the difficulty. If you exclude the errors that were incorporated into the movie, that is. Viewers initially unnoticed these mistakes, which ranged from continuity issues and historical inaccuracies to visible cameramen, but today, they are unavoidable.
Jack and Rose never would’ve met in real life
We suppose we can understand why this small historical aspect was eventually overlooked for the betterment of the plot, since it essentially destroys the entire idea of the film. In reality Jack and Rose would not have crossed paths because he traveled in third class and she in first.
In the past, the purpose of that division went beyond simple class distinctions to include halting the spread of diseases from lower-class passengers (yikes, we know). This implies that Jack was unable to reach the first-class deck in time to save Rose.
