The truth is out there...as any X-Files fan knows. The truth here is that it might be a misnomer to say that Mitch Pileggi is returning to television. Honestly, he never really left.
Pileggi is one of those guys that we see in tons of stuff. Were it not for his longterm role on 'The X-Files', Pileggi might have ended up as one of those "that guy" character actors like Dan Hedaya. Unless, of course, you're a fan of The Shocker.
