Showtime’s Dexter had a killer showing today at San Diego Comic-Con 2011. Ralph Garman introduced the panel, which included Michael C. Hall (as the titular Dark Defender), C.S. Lee (Forensic specialist Masuka), David Zayas (Detective Angel Batista), James Remar (who plays the ghost of Dexter’s dad, Harry Morgan), and this year’s guest star Colin Hanks (who plays newcomer Travis Marshall), along with executive producers John Goldwyn, Sara Colleton, Scott Buck, and Manny Coto.

The panel began with a preview of an upcoming Dexter-themed Facebook game, created by street artist/designer Marc Ecko. Then they played an exclusive preview of the season 6 trailer [watch it here below] featuring guest stars Colin Hanks and Edward James Olmos. There were loads of religious overtones to this year’s killings, and was set to Depeche Mode’s “Personal Jesus.”
