We reported a few weeks back that Sam and Dean Winchester's grandfather will return to the series and now that news has been confirmed along with new details on his return. Ausiello Files, which broke the original story, has confirmed that Mitch Pileggi will return to Supernatural in their upcoming sixth season as Joseph Campbell, grandfather to Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles).
"For one thing, he's a Campbell - from Sam and Dean's mom's side of the family," reminds Gamble, "which, unlike their dad's, has actually been into hunting for a very long time. There's a whole side of Sam and Dean's history that they know nothing about. We'll get to find out a bit about it this season."
The site is also reporting that the show is searching for an an actor for a new character this season named Christian. Here's how the site describes the character.
"In other Supe news, the show is on the prowl for an actor in his late-30s to mid-40s to play the recurring role of Christian. Described as 'capable, calm under pressure, and very good at his job,' Christian has a special relationship to Sam and Dean."
We'll be sure to keep you posted with any further news on Supernatural as soon as we have more information.
