“You can be very lucky and go through life without tragedies hitting you, but that’s incredibly rare. So it’s wonderful to have a show [like 'Call the Midwife'] that is amazingly positive and life affirming, but also deals with all of those everyday tragedies that people have within their own families. Regardless of where you’re from, we are all human and we all have those relationships and terrible things can happen to all of us.”
