Does that familiar whistling theme music make your hairs stand on end?
Well, it's back with the first two-part trailer for the new revival broadcasting in the US on Monday night.
The X-Files returns to Fox on January 24 and the network is already teasing fans with the footage which sees Mulder (David Duchovny) declare, "In 2002 our investigation ceased buy my personal obsession did not."
We then hear him utter the words, "I can't do this alone" as Scully (Gillian Anderson) answers her phone and he says, "I'm here."
Check out a few more familiar faces too...
