Amanda Peet is in the next “X-Files” movie along with the usual David Duchovny and Gillian Anderson. The “I Want to Believe” film is opening July 25th this summer. Peet seems to be playing an FBI agent similar to Mulder.  This trailer doesn’t depict her role as much as the recent theatrical trailer viewed at the official site.  The official trailer offers Peet’s line “I am not the most popular girl at the FBI, right now,” perhaps says it all. Your guess is as good as mine.
