HBO really, really pushed
True Blood at the con.

Titus Pullo! (I mean... Ray Stevenson. And... Darla. Promoting
Punisher: War Zone)

I'm just going to post a few cast pictures from various shows in case anyone is interested.
The River-nator and Sarah Connor (Summer Glau and Lena Heady) from
Terminator: The Sarah Connor Chronicles.
Brian Austin Green (yes, the guy from 90210), Summer Glau, Lena Heady and Thomas Dekker for
Terminator: The Sarah Connor Chronicles.
Some of the cast of
Pushing Daisies: Chi McBride, Ana Friel, and Lee Pace.

Sam and Dean Winchester (Jared Padalecki and Jensen Ackles) and one of the writers from
Supernatural.
