In a 2006 interview, Dame Helen Mirren stated that "what did shock me profoundly was we had a storyline, where a house had been bought and they're re-modelling the garden and they find a dead body and then they find another one. And in my mind I was going - that's a little bit, you know, that's pushing it a bit - and then very shortly after that the Rosemary and Fred West case came about and I thought - my god. My god. Not only was it realistic. The real world went so much further."
