After a nerve-racking and emotionally-jarring fourth season, Showtime’s serial-killer drama “Dexter” is set to return this fall with new characters and dire developments for protagonist Dexter Morgan (Michael C. Hall). A trailer for the show’s upcoming new season was premiered this week at Comic-Con during a “Dexter” panel.

Take a look:

New faces joining the show’s fifth season include Julia Stiles (The Omen), Peter Weller (RoboCop), April Lee Hernandez (“ER”), Maria Doyle Kennedy (“The Tudors”), Johnny Lee Miller (Mindhunters), and Shawn Hatosy (Bad Lieutenant: Port of Call – New Orleans).

“Dexter” is up for multiple awards at this year’s Emmys.

Dexter Morgan is listed as one of Clatto’s 12 Heroes in Horror/Sci-fi That Won’t Make You Feel Like an Asshole.
