(CBS News) James Cameron is perhaps best known as the Oscar-winning director of "Titanic," but he's also an avid researcher of the ship.
On "CBS This Morning: Saturday" - on the 100th anniversary of the "unsinkable" ocean liner's collision with an iceberg - he was asked what lures people (including himself) to the tragic story a century after its sinking.
He said that what gets people is the separation people endured when the Titanic was submerging. "It's death in slow motion," Cameron said.
"People had to say good-bye to their family members, their loved ones, as the boats were being lowered. That image will endure for a thousand years, I think," he said.
