The truth is out there - or is it?

A new trailer for Fox's X-Files revival shows Agent Fox Mulder (David Duchovny) starting to have doubts about his life's work.

"What if our work, the X-Files, everything we've been led to believe in, is a lie?" Mulder asks in the 30-second clip, which premiered during Gotham on Monday night.

The six-episode event series, which premieres on Sunday, Jan. 24 after the NFC championship game, reunites Mulder and his partner, Agent Dana Scully (Gillian Anderson) as they investigate paranormal activities. The first episode premiered at New York Comic-Con earlier this month.
