The comic’s Adrian Veidt hadn’t cloned any human beings, at least assumedly, but his iconic pet Bubastis was indeed genetically created.
The lynx reappeared in the Doomsday Clock series, despite getting obliterated in the original storyline, implying it was a clone.
It was very curious why “everyone else” remained unseen, or made to wear masks, as it went with the musicians and stagehands during the play performance.
I love that Watchmen only took two episodes to set up and reveal that maybe-Veidt’s various assistants are all cloned versions of the same male and female played respectively by Sleepy Hollow’s Tom Mison and Endeavour’s Sara Vickers.
