The television adaptation of Good Omens, currently streaming on Amazon Prime, is apparently doing very well. The executive team behind the show recently told Deadline that they would love for the series to continue. That’s not something they do with flops, so this must be a testament to how well the show is doing ratings-wise. (Unlike Netflix, Amazon does not release viewer statistics.) Like many studios, Amazon was betting on the built-in audience of a much-loved property to get their hands on a hit. It must have worked.

The 1990 collaboration Good Omens, co-authored by Neil Gaiman and the late Terry Pratchett, is about the birth of Satan’s son, which heralds in the End of Times. An angel named Aziraphale and a demon named Crowley conspire to prevent the end of the world because, well, they’ve been roaming the Earth for centuries and kind of like it. Its tongue-in-cheek delivery is why Good Omens is the thing many people point to when they say “British literary satire.”

In the Amazon series, Aziraphale is played my Michael Sheen and Crowley by David Tennant. Buzz for the six-episode series been very positive and the producers want more. The series co-creator, Vernon Sanders, said that they would love revisit the world and see more stories set there. “It’s in Neil’s hands now but we’d love to do it,” Sanders told the Television Critics Association.

What could that mean? It could mean that this is an open doorway for the unfinished sequel that Gaiman and Pratchett had apparently conceived and plotted. The working title of that sequel was 668—The Neighbour of the Beast, but it was never completed. The story involved “a lot more angels,” as Gaiman wrote in his appreciation for his co-author following Pratchett’s death in 2015.

Although Gaiman also noted then that he doubted if the sequel would ever be written, I can’t help but think it would be a fitting love letter to Pratchett. Gaiman holds Pratchett in very high regard. During the world premiere of Good Omens, Gaiman paid tribute to Pratchett by reserving a front-row seat for him at the jam-packed theater and using it to prop up Pratchett’s trademark hat. He would have loved that.
