As the epic drama Game of Thrones is coming to an end, HBO has been at work developing a new series that will hopefully have the same devoted following and critical acclaim. HBO has released the official trailer of The Watchmen, based on the comic book saga of the same name by Alan Moore and Dave Gibbons and published by DC Comics in the 1980s.

Set in the mid-‘80s, the story of Watchmen concerns the mysterious murders of retired superheroes carried out by an unknown assailant. Rorschach, a ruthless masked vigilante, begins a temporary reunion of his former “Minutemen” colleagues to find out who is targeting them and why.

According to the description by Deadline, the dark series in an alternate history where superheroes are viewed as outlaws, the new drama from executive producer Damon Lindelof is rooted in the same universe as the source material but strikes out in new directions with unfamiliar characters and a different story to tell. The cast includes: Academy Award-winner Regina King, Jeremy Irons, Don Johnson, Jean Smart, Tim Blake Nelson, Louis Gossett Jr., Yahya Abdul-Mateen II, Hong Chau, Andrew Howard, Tom Mison, Frances Fisher, Jacob Ming-Trent, Sara Vickers, Dylan Schombing, and James Wolk.

Explaining his fondness for the comic book series, Lindelof said, “Those original twelve issues are our Old Testament. When the New Testament came along it did not erase what came before it. Creation. The Garden of Eden. Abraham and Isaac. The Flood. It all happened. And so it will be with ‘Watchmen.’ To be clear, Watchmen is canon. Just the way Mr. Moore wrote it, the way Mr. Gibbons drew it and the way the brilliant John Higgins colored it.”

Although the Watchmen was released as a feature film in 2009, fans of the comic book gave it a lukewarm response. No date for the premiere has been released
