After seven years since she had last played Dana Scully, The X-Files star Gillian Anderson found herself struggling a bit to get back into character for Fox's six-episode revival.

"I forgot the style of acting. I forgot how to speak the style of writing, since it's different than what I've done since," Anderson tells TVGuide.com in the video above. "And also playing her at the age that I am as opposed to the age that I was, I had to give myself permission for that."

The X-Files airs Mondays at 8/7c on Fox.
