The crew discovered that the leaded glass in the First Class dining room was amazingly intact; director Cameron had the clever idea of maneuvering his sub outside the ship so the ROV could pick up its lights through the glass from the inside. The composite image below shows the First Class dining room before the wreck, and as it is today.
The First-Class dining room then and now.
The crew made other surprising discoveries, such as a wooden wash stand with a decanter and glass not only intact, but still upright where they were set some 80 years ago. They also conducted extensive explorations of the shattered stern section, which did not appear in the dramatic film (Unlike the reasonably intact bow, the stern's a mess; a tangle of twisted metal).
The gigantic IMAX presentation is impressive. Less so is the 3-D effect; it's pretty cool when Cameron just lets it happen, instead of doing the obligatory thrust-something-out-at-the-audience trick. The illusion of a 3-D ocean was well done, and the effect -- combined with the high-intensity lighting that allowed a depth of field never before achieved -- gave a marvelous sense of presence to the wreck. However, the film could have stood on its own without the 3-D effect, as I expect it will upon its DVD release.
Overall I was pleased with Ghosts of the Abyss and recommend you check it out if it comes to an IMAX theater near you. For a second opinion, here's an MSNBC article on the filming, and reviews at MSNBC and the Chicago Sun-Times.
