I have been a student of the Titanic sinking since before the wreck was found. I agree that A Night To Remember is the definitive Titanic film. Most of the others rely on some sort of fictional subplot to keep the audience interested. I have several different Titanic films/mini series on DVD, including Cameron’s version, and from a historical standpoint, Cameron got the basic history and the ship itself mostly correct. Some of the others are so far from accurate that I end up laughing while watching. I saw Titanic in the theater probably a half dozen times, just because of how lifelike the ship appeared, almost like you were on board yourself.
I think the scenes that got to me the most were the shot of the stern coming back down to settle in the water after the separation (a little overdone, because the angle probably wasn’t that acute, but for those already in the water it certainly may have appeared that way) and then the stern itself rising and sinking (again, based on research it probably sank at a shallower angle, but for the people still on the ship, it probably felt like the movie portrayed it).
Since I was not invested in the Jack/Rose romance, I don’t recall shedding any tears on their account. I always felt the wood panel scene was representative of the people who tried to use the wood deck chairs as floatation devices, and they didn’t have a lot of buoyancy. I did feel sad in that last scene as it brought home how many people perished on the ship. It’s one thing to hear a number. It’s another to have that number represented visually by actual people.
