Fox's promo for the X-Files massive online rewatch showed us the first footage from the upcoming six-part event series.
The X-Files Twitter page announced that the network will be counting down the 201 days until the 2016 revival by revisiting an episode a day of the original series (The episodes are currently available to stream via Amazon Prime, Hulu and Netflix, and the entire series is available on DVD. There are no plans, as of now, to put the episodes on Fox's On Demand or digital app.)
The trailer for the rewatch includes the first new footage of Mulder (David Duchovny) and Scully (Gillian Anderson). You can see them searching for something in the dark at the 32-second mark in the video below:
