Tick tock goes the Doomsday clock.

HBO has unveiled the first teaser for "Watchmen," Damon Lindelof's high-profile "remix" of the classic graphic novel by Alan Moore and Dave Gibbons.

The series draws from the comic's universe and set in an alternate history, where superheroes are treated as outlaws, but goes its own way with new characters and new stories. It appears to take place several years after the colossal disaster that occurred near the end of the comic.

The teaser indicates superheroes have gone into "hibernation" but are reemerging. And there's about to be a major reckoning — from an army of Rorschach disciples acting as vigilantes.

The teaser provides glimpses at an aging Ozymandias (Jeremy Irons), the engineer of that disaster; Regina King suiting up as Angela Abraham; Don Johnson's police chief; Jean Smart as Agent Blake; and Tim Blake Nelson as Looking Glass.

"Watchmen" premieres this fall on HBO.
