The X-Files premiere date: Leaked set pictures hint at Mulder and Scully working on a UFO case

New behind-the-scenes photos from The X-Files reboot series have leaked online.

A picture from the crew's night shooting scenes in Ashcroft, Columbia, shows a flying saucer embedded in the ground, and the scene looks like a UFO crash site.

The Vancouver Sun reported that Ashcroft, with its semi-desert terrain, may be standing in for Roswell, New Mexico, a supposed UFO crash site, which is a big part of the X-Files mythology.

Gareth Smart, who shared the picture on Facebook, told the website, "Ashcroft has the Wilderness Way Resort zipline park and they are filming right on their land. The X-File crew is staying at their resort...It's my understanding that they are filming a whole whack of stuff at night."

It should be noted that when the television series came to an end in 2002, it left a major plotline unresolved. Fox Mulder (David Duchovny) learned the truth about a massive alien invasion that would happen on 22 December 2012.

With the series returning, and a UFO crash being spotted, it could mean Mulder and Skully's first case is about an alien invasion.

David Duchovny and Gillian Anderson will reprise their roles as Mulder and Scully respectively in the Fox series. The X-Files reboot, helmed by the original series creator and executive producer Chris Carter, is set to premiere on 24 January 2016 on Fox.

The six-episode season counts as the show's 10th season, and will air 13 years after the show ended.

"I think of it as a 13-year commercial break," Carter said in a statement when the new series was announced. "The good news is the world has only gotten that much stranger, a perfect time to tell these six stories."
