No, Jack does not survive or come back from the dead in the 1997 film Titanic. A fan created a fake trailer for a nonexistent movie called Titanic 2: The Surface, in which Jack is discovered 100 years later, frozen and unconscious but still alive, and is thawed out to live in the future. But this is not part of the official storyline for the film.

The movie character "Rose DeWitt Bukater", played by Kate Winslet (young Rose) and Gloria Stuart (old Rose) in the movie "Titanic", changed her name to "Rose Dawson" after being rescued in the movie, wanting to begin life anew and to honor the person she truly loved, Jack Dawson, who had helped to save her life. Rose dies peacefully in her sleep at the very end of the movie, onboard the vessel conducting salvage operations on the Titanic. The ending scene depicts her spirit returning to the Titanic and those that perished, including her former love Jack Dawson.
