In fact, there are now two trailers out there. We had the teaser trailer, and now - between last night's episodes of Gotham and Minority Report - Fox released two trailers for the new series. It's rumoured that the first episode is due to debut for fans at New York Comic Con on October 10th, with the series kicking off in January. 

This here first trailer aired during Gotham - the sound is ropey, but Mulder's sentiment about his "personal obsession" is the same...

This second trailer, aired during Minority Report - and it is infinitely more exciting, featuring Walter Skinner and a cameo by the Cigarette-Smoking Man. 

We've NEVER been in more danger, people.
