‘Supernatural’s’ Jared Padalecki And Jensen Ackles Welcome Guest Star Liane Balaban [PHOTOS]

Jared Padalecki, Jensen Ackles and Liane Balaban – who has a guest arc this upcoming season – shot scenes on the first day of filming Supernatural’s season eight in Vancouver, British Columbia yesterday (July 10th).

Balaban will play a doctor, described by the CW (via Zap2it) as “a tragedy-damaged soul” who “soon reveals herself to be a brave, sweet, smart, sarcastic woman.”  Balaban will play Sam’s (Padalecki) love interest, though she’ll put up a good fight in the beginning.

Who’s getting fired up for 2012 San Diego Comic Con?  On Sunday, July 15th,  Supernatural’s panel will be held at 11:15am in Hall H, according to TVEquals.com.
