Taking a stroll down conspiracy lane finds a new entrant. This has nothing to do with the real Titanic but the fictional retelling in James Cameron’s Titanic. If you have seen this Academy Award winning movie, you know the story of Jack and Rose. But some out there, perhaps with lots of time to spend with nothing to do, are putting out the theory that Jack was simply made up by Rose. The thinking is this: since she was being trapped into a marriage she did not want, she created the delusion of Jack. While it is plausible in some senses, it begs the question of who painted her (did she paint herself?)or how he was seen by others at a dinner. Then again these are inconvenient truths for the conspiracy minded.
