National Geographic Video: Secrets of the Titanic

I went through a brief Titanic phase as a teen and it was largely due to this special. Here, the grand oceanliner is portrayed as a monument to human achievement, and then the film promptly plunges you into the deep to survey what remains of her today (in '86 at least). The sight of the ruins almost make this kind of a ghost story, by virtue of the robotic camera footage and Martin Sheen's server narration detail of the ship's final moments before sinking. This is a fascinating documentary and an excellent starting point in anyone's Titanic research.
