Warner Bros. Entertainment is the key to excitement at the forthcoming San Diego Comic-Con. This marks the fifth consecutive year for the studio’s popular room “key program,” giving fans instant access to a usable — and collectible — piece of artwork.

Over 40,000 branded room keys will be available to fans at 38 participating San Diego–area hotels, courtesy of Warner Bros. Worldwide Television Marketing. For Comic-Con 2012, Warner Bros. has created all-new keycards for three of the Studio’s highly anticipated new fall series:

The “666 Park Avenue” keycard grants access to anything you desire — as long as it’s inside your room
The “Arrow” keycard features star Stephen Amell as the Arrow in an all-new in-character photo
The “Revolution” keycard opens hotel doors every time — no blackout here!

“666 Park Avenue”: Anything you desire can be yours … for a price. “Lost”’s Terry O’Quinn and “Desperate Housewives”’ Vanessa Williams headline this scary, seductive drama from Alloy Entertainment as the owners of a Manhattan apartment building who recruit an idealistic young couple to manage the historic site with a dark history. The series also stars Rachael Taylor (“Charlie’s Angels”), Dave Annable (“Brothers & Sisters”), Robert Buckley (“One Tree Hill”), Mercedes Masohn (“The Finder”), Helena Mattsson (Iron Man 2) and Samantha Logan (“Law & Order: SVU”). Matthew Miller (“Chuck”), David Wilcox (“Fringe”), Leslie Morgenstein (“The Vampire Diaries”), Gina Girolamo (“The Secret Circle”) and Alex Graves (“Fringe”) are the executive producers. Based upon the book series by Gabriella Pierce and from Bonanza Productions Inc. in association with Alloy Entertainment and Warner Bros. Television, “666 Park Avenue” will air Sundays at 10/9c on ABC this fall. Watch the full-length pilot at Warner Bros. Television’s Preview Night screening at Comic-Con on Wednesday, July 11, or during the “666 Park Avenue” session on Friday, July 13.

“Arrow”: From executive producers Greg Berlanti (Green Lantern), Marc Guggenheim (Green Lantern), Andrew Kreisberg (“Fringe”) and David Nutter (“Smallville”), hard-hitting action series “Arrow” reinvents the DC Comics hero. After being marooned for five years on a remote island, billionaire Oliver Queen returns home with a mysterious agenda and a very lethal new set of skills that he uses in a war on crime. The series stars Stephen Amell (“Private Practice”), Colin Donnell (“Pan Am”), Katie Cassidy (“Supernatural”), David Ramsey (“Dexter”), Willa Holland (“The O.C.”) with Susanna Thompson (“Dragonfly”) and Paul Blackthorne (“The River”).

“Revolution”: What would you do without it all? In “Revolution”, an epic adventure thriller from “Supernatural”’s Eric Kripke, J.J. Abrams’ Bad Robot Productions and Iron Man’s Jon Favreau, a family struggles to reunite in a post-apocalyptic landscape of empty cities, local militias and heroic freedom fighters where every single piece of technology — phones, computers, cars, even lights — has mysteriously blacked out … forever. “Revolution” stars Billy Burke (Twilight films), Tracy Spiridakos (“Being Human”), Anna Lise Phillips (Animal Kingdom), Zak Orth (Wet Hot American Summer), Graham Rogers (“Memphis Beat”), J.D. Pardo (The Twilight Saga: Breaking Dawn – Part 2), Giancarlo Esposito (“Breaking Bad), David Lyons (“The Cape”), Maria Howell (“The Vampire Diaries”) and Tim Guinee (Iron Man films) and is executive produced by Kripke, J.J. Abrams (“Fringe”) and Bryan Burk (“Fringe”). Favreau directed the pilot and will serve as co-executive producer of the series, with Kathy Lingg (“Fringe”) and producer Athena Wickham (“Fringe”).
