NBC and Universal TV are threatening to invade Comic-Con with their new series Constantine, adapted from DC’s Hellblazer comic (and not the Keanu Reeves film version). The pilot episode of series debuting Oct. 24 will be screened during Wednesday’s Preview Night before a 3D Constantine “experience” in the Gaslamp opens to fans. The show will have a panel and pilot screening on Saturday at 5:15 PM in Room 6BCF with cast members Matt Ryan, Harold Perrineau and Charles Halford, as well as executive producers David S. Goyer and Daniel Cerone in attendance.

Star James Spader will front the panel for last season’s newbie hit The Blacklist to tease the upcoming second season on Saturday at 1:45 PM in Room 6A with executive producers Jon Bokenkamp and John Eisendrath. Last year’s promo around downtown San Diego proved fruitful and this year the show will take over the Tin Fish Restaurant in the Gaslamp from Thursday to Sunday.

Grimm fans will get what’s only being described as an “exclusive video” during Saturday’s 3PM panel in Ballroom 20, where cast members David Giuntoli, Russell Hornsby, Bitsie Tulloch, Silas Weir Mitchell, Sasha Roiz, Reggie Lee, Bree Turner and Claire Coffee will join EPs David Greenwalt, Jim Kouf and Norberto Barba for a Q&A.

Thursday at 4:45PM Hannibal‘s supporting cast and EPs will hit Ballroom 20, although leads Mads Mikkelsen and Hugh Dancy are not scheduled to appear alongside co-stars Caroline Dhavernas, Aaron Abrams and Scott Thompson. Bryan Fuller, Martha De Laurentiis, Steve Lightfoot and David Slade will also participate in the panel moderated by UK talk show host Jonathan Ross.

Bates Motel‘s Emmy-nominated Vera Farmiga will hit Room 6A on Friday at 3:30PM to preview next year’s third season alongside EPs Carlton Cuse and Kerry Ehrin and co-stars Freddie Highmore, Olivia Cooke and Nestor Carbonell.

Upcoming Adult Swim co-stars Jack McBrayer and Triumph the Insult Comic Dog will appear across the walkway at the Hilton San Diego Bayfront on Friday at 1PM to tease their upcoming live-action comedy series, which premieres in 2015. Triumph co-creator/voice Robert Smigel will join co-creator Michael Koman as they and McBrayer turn in early promo duties.
