Mitch Pileggi has confirmed that he is set to reprise his role as FBI Assistant Director Walter Skinner in Fox's upcoming revival of "The X-Files" franchise. David Duchovny previously hinted at the character's return last month during a Letterman appearance. Having been with the show since the beginning, Skinner essentially became the most well-known supporting character in the franchise alongside the Cigarette-Smoking Man. Skinner was last seen in a cameo in the 2008 film "The X-Files: I Want to Believe". Source: EW
