Liam Neeson opens up about wife Natasha Richardson's death

Liam Neeson, usually so private, was very emotional discussing his wife Natasha Richardson's death on last night's "60 Minutes."

"[Her death] was never real. It still kind of isn't," he said. "There's periods now in our New York residence when I hear the door opening, especially the first couple of years . . . anytime I hear that door opening, I still think I'm going to hear her."

Neeson then recalled his last visit to the Canadian hospital where Richardson was sent after her skiing accident in 2009. "She was on life support," Neeson said. "I told her I loved her, said, 'Sweetie, you're not coming back from this, you've banged your head . . . she and I had made a pact, if any of us got into a vegetative state that we'd pull the plug . . . that was my immediate thought, 'OK, these tubes have to go. She's gone.' "

Neeson said three of Richardson's organs were donated to others, which would have pleased her.

He added that his grief is still not fully gone. "It hits you," he says. "It's like a wave. You just get this profound feeling of instability -- the Earth isn't stable anymore, and then it passes and it becomes more infrequent, but I still get it sometimes."
