"The X-Files" has never been a show afraid to take on the unknown, whether it's aliens, people with powers, monsters, or other things that go bump in the night. However, when the show returns to Fox in a few weeks, the revival miniseries will cover controversial conspiracy theories involving a U.N. takeover and the 9/11 terrorist attacks.

In an interview with Entertainment Weekly, show creator Chris Carter said the show will introduce a conspiracy that suggests a military group will "take over America" for a U.N. like group. This idea will be introduced to the show by a character named Tad O'Malley, who is a web series host played by former host of "The Soup" Joel McHale. On the show O'Malley suggests that 9/11 was a "false flag operation" that ties into a government cover up of a UFO crash in Roswell.

Carter said the post 9/11 world involving the admitted spying by the government isn't something the show is making up and people have given up right to remain protected following the terrorist attacks. Today's world gives Carter and the show plenty of new material to work with.

"People know the show deals with science and fact and also deals with far-flung theories about not only the supernatural but government conspiracies. It throws out as many questions as it does answers," Carter said. "And I have to say what it’s done for me and the writers it has given us a whole new open field which to run. It’s given the show an interesting new life and context that it might not have had in 2002."

Gillian Anderson, who stars as Dana Scully on the show, recently teased the idea of the series taking on different ideas than it did when it was last on the air in 2002. She told Vulture "The X-Files" will have a "familiar feel," but will dive into some new waters.

"Things have changed so much since we did it—politically. I mean, the climate is such that it makes it possible," Anderson said. "The show has always had a political element to it — we often speak about the government being dishonest."

When the show originally aired, the biggest conspiracy Scully and Fox Mulder (David Duchovny) dealt with was the government covering up the knowledge that aliens existed. The first minute of the "The X-Files" miniseries was released Monday, which revisits this theory. However, the first episode will push the theory involving the government even further. 

"The X-Files" revival premieres Sunday, Jan. 24, on Fox following the NFC Championship game.
