Director James Cameron does everything on a mammoth scale. After viewing this DVD, I wish I had seen the 3-D version. This is an exhaustive search of the remains of the Titanic. The inner portions of the ship are explored with two mini robots and the two submersibles with the director, actor Bill Paxton and the crew members aboard. This is at over 2.5 miles deep. Paxton adds some human humor/drama with the crew, but the real star is the ship. Starting from the stormy surface waters to the calm, eerie depths of the North Atlantic, Cameron leaves nothing out. There are still glasses and plates peacefully resting where they were left on that fateful night. Brass beds lay intact. Particular rooms of celebrity passengers are found with items left as they were. This is miraculous, as the ship spun wildly around in its' decent, spewing debris everywhere. Stained glass is still intact everywhere and the robot lights cast magical colors and shadows throughout. Cameron puts everything in perspective by frequently superimposing transparent actors dressed in period clothes strolling the deck. These "ghosts" add true scale to the Titanic.
The 90-minute version adds more information about the sea-life existing around the Titanic with comments from Dr. Lori Johnston. More of the Captain's personal life is explored as well as life aboard the state of the art research vessel. The 'making of' feature, "Reflections of the Deep" is interesting and includes some more information, but not a great deal more insight. "The ROV Experience" is more for the technically minded, but fun to experience. For extras, not much beats this collection, but glorious excess is what James Cameron is all about and he does justice to the Titanic.
Footnote: Towards the completion of the exploration, the crew heard about the attacks of 9/11. This was an all too eerie coincidence considering the massive tragedy of the Titanic that had been waiting decades to be explored
