NO!!! they just put them in there to make it interesting so that they cud sell lots of tickets which they did but no jack and rose were not real people

no is not true

No their story is not true. And they weren't real people either. The people who wrote the movie script added them so it would make it interesting and get more views. Also its a love story and most girls like love stories so that is one way how they would get more views.

Hope I could Help!!

No, the story of Jack and Rose is not true. However, director James Cameron did discover after he'd created the movie that there had been a J. Dawson on the Titanic. This J. Dawson worked in the boiler room and was not a "passenger". J. Dawson's grave is the most visited of those who died in the tragedy because of this movie.
