Television and DC Entertainment will present a three-hour event in Hall H featuring some of DC Comics's greatest characters. Kicking off the exclusive evening is the world premiere public screening of the highly anticipated new drama seriesGotham, allowing fans their first trip into the dangerous and compelling world of the iconic city. This will be the only screening of Gotham at Comic-Con, and it will be followed by a screening of the complete pilot episode of new action-drama The Flash, as well as exclusive video presentations of returning hit Arrow and new thriller Constantine.

Gotham- Before there was Batman, there was Gotham. With a reputation synonymous with law and order, Commissioner James Gordon is one of the crime world's greatest foes. Everyone knows the name. But what is known of Gordon's rise from rookie detective to police commissioner? And what did it take to navigate the layers of corruption that secretly ruled Gotham City, the spawning ground of the world's most iconic villains-the larger-than-life personas who would become Catwoman, The Penguin, The Riddler, Two-Face and The Joker? Gotham is the origin story of the great DC Comics supervillains and vigilantes, revealing a new chapter that has never been told. From executive producer/writer Bruno Heller (The Mentalist, Rome), this one-hour drama follows one cop's rise through a dangerously corrupt city teetering on the edge of evil and chronicles the genesis of one of the most popular superheroes of our time. The series stars Ben McKenzie (Southland, The O.C.), Donal Logue (Sons of Anarchy, Vikings), Sean Pertwee (Elementary), Robin Lord Taylor (The Walking Dead), Erin Richards (Being Human), David Mazouz (Touch),Camren Bicondova, Zabryna Guevara (Burn Notice), Cory Michael Smith (Carol), Victoria Cartagena (The Good Wife), Andrew Stewart-Jones (Person of Interest), and Jada Pinkett Smith (The Matrix films), and is executive produced by Heller, Danny Cannon (Nikita), and John Stephens (Gossip Girl). From Warner Bros. Television, Gotham premieres this fall, Mondays at 8/7c on FOX.

The Flash- From the Arrow creative team of executive producers Greg Berlanti and Andrew Kreisberg and director David Nutter, The Flash is a fast-paced superhero drama that follows the high-speed adventures of the Fastest Man Alive. Written by Berlanti, Kreisberg, and DC Entertainment's chief creative officer Geoff Johns, the action drama follows Central City police scientist Barry Allen, an everyday guy with the heart of a hero and the genuine desire to help others. Standing still emotionally since the day his mother was murdered (and his father unjustly jailed for the crime), Barry was taken in as a child by the investigating Detective West and raised in a cop's home alongside West's super-smart daughter (and Barry's dream girl), Iris. But when an unexpected and devastating accident at the S.T.A.R. Labs Particle Accelerator facility strikes Barry, he finds himself suddenly charged with the incredible power to move at super speeds. While Barry has always been a hero in his soul, his newfound powers have finally given him the ability to act like one. With a winning personality and a smile on his face, Barry Allen-aka The Flash-is finally moving forward in life...very, very fast! The series stars Grant Gustin (Arrow), Candice Patton (The Game), Rick Cosnett (The Vampire Diaries), Danielle Panabaker (Necessary Roughness), Carolos Valdes (on Broadway: Once), with Tom Cavanagh (Ed), and Jesse L. Martin (Law & Order). From Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, The Flash premieres this fall on Tuesdays at 8/7c on The CW.

Constantine- John Constantine is a man waging war against the forces of darkness -from both within himself and the outside world. An irreverent, working-class con man and occult expert, he's an experienced exorcist and demonologist with an extensive list of supernatural contacts, each with their own paranormal talents and abilities. Following the aftermath of a tragic incident, Constantine has voluntarily checked himself into an asylum and sworn off investigating matters of the supernatural, but when a cryptic message calls him out to reluctantly resume his old life, he finds himself saving the life of a young woman whom he's never met but is connected to in a very important way. With dark forces gathering power in the world, Constantine allies himself with Manny, a rogue warrior angel, and his giant childhood protector, Chas-the only friend who's managed to stay alive. Based on characters published by DC Entertainment, Constantine reflects the lore of the fan-favorite comic, combining noirish storytelling with the evolving mythology of John Constantine, a morally challenged character who doesn't come down on the side of either good or evil...but ultimately might be the only thing defending us against the dark forces from beyond. The series stars Matt Ryan (Criminal Minds: Suspect Behavior), Harold Perrineau (Lost), and Charles Halford (True Detective) and is executive produced by Daniel Cerone (Dexter) and David S. Goyer (The Dark Knight trilogy). From Bonanza Productions Inc. in association with Warner Bros. Television, Constantine will air Fridays at 10/9c on NBC, premiering October 24.

Arrow- Arrow series stars Stephen Amell (Private Practice), Katie Cassidy (Supernatural), David Ramsey (Dexter), Emily Bett Rickards (Flicka: Country Pride), Colton Haynes (Teen Wolf), Willa Holland (The O.C.), Paul Blackthorne (The River), and John Barrowman (Torchwood -- with executive producers Greg Berlanti (The Flash), Marc Guggenheim (Green Lantern), and Andrew Kreisberg (Fringe) -- will take aim at San Diego with a special video presentation and discussion previewing the show's highly anticipated third season. Based upon characters appearing in comic books and graphic novels published by DC Comics, Arrow is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television.
