thought i'd add my 2 cents...in regards to the ultimate Titanic movie..sort of the same angle Michael Standart mentioned earlier, as far as showing more of the outside story..so, instead of filming the story of the Titanic approaching the impending doom, reverse it and show the impending doom approaching the Titanic....you can include scenes of all the little "omens" that occurred prior to the voyage, and even show the dreaded iceberg going "topsy turvy" in the dark, moments before impact...(heck, you might even go as far as beginning the movie in "1910", showing the iceberg breaking off the glacier to begin it's journey !!)
just a thought..
