Yeah, well, I just looked up on the Inspired by true events and this is what I got:
“I mean there are a lot of Cyruses out there. Remember, when Albert says ‘At any given time the FBI says there are 30 to 50 serial killers operating in the US.’ That’s a real number.†And it is – as are all the other statistics and facts in Cyrus.
But, perhaps the best place to start is the beginning rather than the end. I had been doing a lot of research on serial killers for another project – and the real facts and stories of these people were absolutely horrifying. What makes them tick? Where do they come from? What they do to their victims and why? At the same time, I was driving to a horror convention in Minnesota to talk and passed by a creepy deserted farm house. The thought hit me – what if all the things I had been reading about took place in that house – it sent chills down my spine. So the next day I sat down and wrote a short story called “Roadkill†based on my research and the house – and that turned into Cyrus."
So, as expected, it was a compilation brought about by a group of crimes that may or may not have taken place at one place or another....
More bullshit. I wish filmakers would quit this nonsense. The Girl Next Door...Jack Ketchum wrote a novel based on real events. Two movies were made about said events. Both were pretty damn good. Bummer, I thought that maybe there was a good urban legend based on one particular individual. Apparently not. Oh well.
