"People saying, 'Thanks for making me laugh today, it's been bloody grim at my place.'

And while most have missed being able to hug others during the pandemic, the 72-year-old actor insists he hasn't as he's "not a man-hugger".
He added: "Look, I went to boarding school for God's sake. At the end of the holidays, I'd catch the train back to school and my father and I would shake hands at the station. That was me, at nine years of age. 'Goodbye, Dad.' 'Goodbye, old boy.' Wouldn't see him again for three months. So, no. I do not hug easily or comfortably. I'm not a man-hugger, let's put it that way."
Neill found the crisis "strangely energising", but says there are some people now who are struggling more now as they are missing lockdown.
Speaking to The Guardian newspaper, he shared: "The full-blown crisis was strangely energising. I've spoken to people who are missing lockdown; they liked being at home, and now we're in this no-man's land where no one knows, and we're getting mixed messages from people in charge. There's the impulse to think: 'Well, that's done and dusted.' And, of course, it isn't."
