"They are amazing," wrote Gaiman, who serves as showunner of the miniseres. "This is them in the opening scenes, 11 years ago, in St James's Park. David and Michael, demon & angel."

Based on the 1990 novel by Gaiman and the late Terry Pratchett, Good Omens is a comedic take of the coming of the apocalypse. It centers on the angel Aziraphale and the demon Crowley, who attempt to short-circuit the End Times, and the Antichrist who, because of a mixup at the hospital, is a seemingly normal boy raised by English parents.

The photo arrives on the heels of the additions to the cast of Jack Whitehall of unfulfilled wage clerk turned witch-hunter Newton Pulsifer, Michael McKean as witch-finder Sgt. Shadwell, and Miranda Richardson as psychic medium Madame Tracy.

Good Omens will premiere worldwide in 2019 Amazon Prime Video ahead of its broadcast on BBC Two.
