From here, his film career soon took off.

Unfortunately, he wasn’t unfamiliar with the pain of tragedy.

“I’m like Herman Munster,” he told the outlet (viaNDTV.com).

Just suddenly … the Earth isn’t stable anymore.

And then it passes and becomes more infrequent, but I still get it sometimes.”

However, Neeson has found a way to feel connected to his late wife.

“I go down there quite often, so I do speak to her as if she’s here.

Not that she answers me.”

“It was like, ‘Wait a minute …

This isn’t a good example for my boys, so I’m just going to quietly stop.

Not going to announce it.

Just quietly stop.’

And I did.”

“That was kind of strange it was kind of surreal.”
