I Want To Believe...

"" (Watch on YouTube)

EDIT: In case you're now scratching your head in puzzlement (as you can no longer watch the embedded video), it was a trailer for the new X-Files miniseries which is due to air in January 2016 and which, as you may imagine, I am very, very excited/anxious about. Except now it's gone, seemingly as part of some sort of recherché advertising strategy on the part of the makers.

This article may shed light on the matter (you can also watch a new trailer there with some of the same footage as the old one):
