Day One is an upcoming NBC Universal 13-episode sci-fi television series about apartment residents that survive an unknown world-wide cataclysm.
It will be directed by Alex Graves whose notable work includes the pilot episode for both Fox's Fringe and Journeyman.
No premiere date has been given, but due to comments made by NBC's Angela Bromstad, the show is expected to fill the Heroes time slot, saying, "‘Day One’ is a big event and we're looking at that to come into the 'Heroes' spot," Bromstad told the Reporter. "It's right now being looked at as a 13-episode run -- something people could commit to and we could make a big splash with."
