You may know him as FBI Assistant Director Walter Skinner on “The X-Files” or, more recently, you may have thrilled to his recurring role on “Stargate: Atlantis” as Col. Steven Caldwell, but either way, if you’re a sci-fi fan, you probably recognize the face of Mitch Pileggi. Pileggi’s resume is wide and varied – he’s recently popped up FX’s “Sons of Anarchy,” has turned up on CBS’s “CSI” and “Cold Case,” and was a regular on ABC’s short-lived (but thoroughly brilliant) “Daybreak” – but now it’s The CW’s turn. After a one-off turn on “Reaper,” Pileggi has found his way onto a flashback episode of “Supernatural,” playing Sam and Dean’s grandfather. We spoke to Pileggi in conjunction with the episode, which airs on Oct. 2nd, which gave him the opportunity to praise the cast of that show, speak to the variety of work he’s done, and stand bemused at people’s fondness for his 1989 cinematic collaboration with Wes Craven.
