When "The X Files" ended its successful nine-year run in 2002, fans thought they'd seen the last of FBI paranormal investigators Dana Scully and Fox Mulder.

The show did produce a less successful spin-off, "The Lone Gunmen," in 2001 and two feature films: 1998's "The X-Files: Fight The Future" and "The X-Files: I Want To Believe" in 2008. While the first film was met with a warm reception, its follow-up faltered in comparison, halting any subsequent plans to keep the franchise alive in theaters.

Now after a seven-year hiatus, the dynamic alien-hunting duo is back, and believe us, it's worth the wait.

"We would have liked to have kept the movies going," Executive Producer Glen Morgan revealed at an exclusive screening of the new series' first episode in Los Angeles on Oct. 29. "So when Chris [Carter] called me and said, "Let's try and get the band back together..."

They did just that, and with the exception of a few busy key players, much of the original crew, along with the cast members, have returned, aiding the shows original feel.

"We approached it very much how it was in the first couple of years, so we're really going back to when the show started," continued Morgan. "That was important to Chris."

Where we pick up, life is very different for agents Scully (Gillian Anderson) and Mulder (David Duchovny). She's returned to medicine while he's severed ties with the FBI and is not in the best place personally. Enter Tad O'Malley (Joel McHale), a conspiracy theorist web-TV show host ready to blow the lid on the government's alien cover-up and finally put "the truth out there."

Enlisting the original investigators of "The X-Files" seems like the best way to do that, and when he presents them with the "key," a young woman named Sveta (Annet Mahendru), it's soon business as usual for the intrepid investigators.

"I thought they had the wrong number when they called me," Mahendru revealed to HNGN exclusively. "They called my people and wanted me for it; I was like really? I went to meet Chris Carter and I thought I blew the meeting. I was so freaked out that I was sitting with Chris Carter, so walked out saying, 'Guys this was one of my worst meetings ever.'"

Carter, however, saw something in the actress, who is best known for her role as Nina Krilova on FX's series "The Americans", and gave the self-admitted "X-Files" fan the part.

"It was a trip," she continued. "I watched the show as a teen so the whole time all I was thinking was I'm sitting with Scully and Mulder. But I had to play it really cool and couldn't be too excited."

While Mahendru did manage to compose herself, she admitted that seeing the duo reunited before her eyes did get emotional.

"It was emotional for me and for them and Chris," she explained of watching the iconic duo of Anderson and Duchovny work together. "There's a scene were they are having a conversation and my character is standing back behind the door. I was just so happy and excited, but really had to just be normal."

"It's like you can't believe that so many years later, like a decade later, they're back and right back where they were," she said. "They're coming back to something that was so special and innocent when it first started."

Despite this limited series following a slightly different format to the original series (episode's one and six are tied together, while the other four are stand-alone), Mahendru admitted, "It's like watching a great movie. I can't wait to see the rest of them."

And when it comes to more "X-Files", she's in hope just like the legion of fans anticipating the new series.

"It would be sad if there weren't more," she said. "I don't know, but I do think it's back and not going anywhere. It such a legendary story and for me can't go away."
