Some 13 years after the credits rolled on the final episode, the X-Files still remains one of the most iconic and boundary-pushing TV shows to ever grace our screens. Over its 9 year run on Fox it astounded audiences with its 202 episodes of alien abduction, government conspiracy, and things that go bump in the night - spawning three movies and a spin-off show on its way. At the time the longest running sci-fi series in US history, and now with one of the biggest cult followings in the world, barely a week goes by without another rumour of a reboot or a revival. Even today, its influence on prime time TV can be seen, with the creators behind Lost, Desperate Housewives, Fringe, Millennium, and Warehouse 13 all speaking of their love for the show and how they took elements of it for their own. The show made us see television (and the night sky) in an entirely different way, but some of the most astonishing facts aren't about the monsters, ghouls, or shady government agencies that featured in the stories, but about what went on behind the camera. Bizarre cameos, painting a quarry, and even predicting America's worst terrorist attack, sometimes the truth of the show was stranger than the fiction.
