The writers of HBO's new series "Watchmen" finally rounded up together. Executive producer Damon Lindelof teased that the first day of work kicked off on Monday, Sept. 18 with a photo taken from the writers' room.

Damon Lindelof shared an image of a trophy on his Instagram which was familiar to fans of the "Watchmen" comic series. The scribe aptly captioned his image as "Day One" and his followers immediately knew what it meant.

The said trophy appeared on the cover issue of the "Watchmen" comics #8. Nite Owl received this trophy when he retired as a superhero but the same statuette was also used as a weapon to kill him.

Damon Lindelof was paying homage to the source material in his photo post while confirming that the "Watchmen" series has begun its pre-production.

Developing the TV show

Zack Snyder was originally attached to develop the series in 2015 with HBO. But he was working on "Justice League" then, thus the project fell through.

Snyder adapted "Watchmen" on the big screen back in 2009. It starred Malin Akerman (Laurie Jupiter), Billy Crudup (Dr. Manhattan), Jeffrey Dean Morgan (Edward Blake) and Patrick Wilson (Nite Owl), and earned $185.3 million at the box office.

In June, Damon Lindelof said via Entertainment Weekly that he's in talks with HBO for the "Watchmen" project. The cable network and the showrunner had a previously successful working relationship via the critically-acclaimed series "The Leftovers" that starred Justin Theroux.

Damon Lindelof's adaptation will be a different iteration from the movie or Snyder's original plans for the show.

HBO did not comment on the said project, hence fans thought that it will no longer happen.

The origin of ‘Watchmen’

Alan Moore and Dave Gibbons created the “Watchmen” comic series in 1986. The story is set in an alternate world where superheroes exist. This world mirrors events in the real world in the 1980s. The comic book creators wanted to bring characters in a radically different way as other superhero series.

"We wanted to show that even the worst of them had something going for them," Alan Moore said during a roundtable discussion in 1988. "Even the best of them had their flaws," Moore added.

It’s still unclear when HBO plans to air “Watchmen.” Cast announcements won’t likely happen until a few months from now and the show won’t likely be on the small screen until 2019.

For now, fans are thrilled that “Watchmen” is moving forward on TV. More news should come as the show’s development is underway.
