TitanicOkay, we understand that when the Titanic sunk a major part of the story was eliminated, so a normal sequel might be a little more difficult than the other films on this list... But it’s not impossible.
Just take a look at the awesome fan-made trailer for a sequel. Jack didn’t die; he was just frozen in ice. In the present, Jack is discovered and is forced to live in a world he knows nothing about. Even though it has pretty much nothing to do with the actual Titanic, it seems like a great idea.
