It's no secret that a lot of crime shows loosely base some of their episode plots on real news stories but as far back as season one there have been stories crop up in the news that eerily resemble episodes of Castle after they air. I remember a story that came to light not long after season 1 ended where a body was found in a car that had been given several parking tickets over a course of a couple of weeks, just like victim in "A Death in the Family".
Of all the Castle episodes to air one would think the zombie episode "Undead Again" would be the the least likely we'd see in actual news headlines but that's exactly what has been taking place over the past couple of weeks after a tragic incident in Florida where a man literally ate off 80% of another man's face. Website Forbes.com looks at whether or not Castle may be to blame for the recent increase in zombie related news stories with their article titled "Zombie Cannibal Apocalypse- CDC Weighs In, But Is ABC's Castle to Blame?"
So maybe it’s a secret government plot, my guess is that it’s a news trend kicked off by the television show Castle. After all, it was late April when Castle and Beckett solved the case of a man beaten to death and partly eaten by a zombie. In the episode, the man was actually high on a synthetic drug and didn’t remember attacking the victim. But, in the show (which aired before the crime in Miami) surveillance cameras caught part of the action, just like in Miami. You can watch the full episode here — it’s the type of story that headlines are ripped from. -- Forbes.com
As they say, any publicity is good publicity, but one has to wonder how the Castle writers feel about being linked to recent reports of zombie attacks!
