Liam Neeson has spoken about the moment his wife Natasha Richardson died and how it still doesn't feel real.
The Taken and Schindler's List star has described having to switch off the actress' life support machine after she was involved in a skiing accident in Canada five years ago.
In an interview with Loaded magazine, Neeson said: "Her death was never real. It still kind of isn't."
The Irish actor said he still expects to hear her when the door opens in his house.
Neeson revealed that he and his wife had made a pact that if they ended up in a vegetative state then they would turn off the machines.
It was thought at first that Richardson, 45, had just suffered a minor head injury when she fell in 2009. But her condition soon deteriorated.
"When I saw her and saw all these tubes and stuff that was my immediate thought, 'OK, these tubes have to go. She's gone'," he said.
The 62-year-old said sometimes his late wife's death hits him like a "wave" when he is working.
"You just get this profound feeling of instability," he said.
Neeson now lives in New York with the couple's two sons Micheal and Daniel.
Part of one of Britain's great theatrical dynasties, Richardson was the daughter of Oscar-winning actress Vanessa Redgrave and the late director Tony Richardson.
She was also the granddaughter of Sir Michael Redgrave and Rachel Kempson, the sister of actress Joely Richardson, and the niece of Lynn Redgrave.
Richardson married Neeson in 1994 after the pair met on the set of the film Nell.
