It took almost thirty years for Neil Gaiman and Terry Pratchett‘s popular novel, Good Omens, was able to make its way to the screen, courtesy of the BBC/Amazon series, starring Michael Sheen and David Tennant. (Filmmakers like Terry Gilliam had been trying for years to crack it as a movie.)

The BBC/Amazon show was always meant to be a single six-episode mini-series with Gaiman adapting the original book himself, but that series also proved so popular that so many more people began discovering the book. Of course, everyone also loved Sheen and Tennant’s amazingly snarky chemistry as arch-rivals, Sheen as the angel Aziraphale and Tennant as the demon Crowley.

The Beat spoke with Sheen earlier in the week for his upcoming Universal fantasy-adventure Dolittle, in which Robert Downey Jr. plays the title role, and we asked him whether we might ever see more of the characters he and Tenant played.

“There was only one book written, and [it’s] such a special project for Neil, because he wrote it with Terry and with Terry no longer being with us, I’m not sure how Neil feels about writing any more without Terry.”

That has probably been known for quite some time, and it’s also been known that Gaiman and Pratchett had spoken in the past about writing something more with the characters, though Sheen is pretty sure that it’ll be up to Neil if he decides to write anything more without his late collaborator.

“I know Neil talked about the idea that Terry had actually talked about further stuff for those characters in that world, but they never actually wrote it. But they had talked about ideas, so it would be completely up to Neil and if he felt able to work on it without Terry. Not that he couldn’t – he’d totally be able to, creatively-speaking, but emotionally, it might be quite difficult.”

That certainly makes sense and maybe if enough people gently nudge Gaiman (who is always busy with a hundred other things) to give it a try, more of these characters could come to fruition in some form or another.

“I haven’t seen Neil for a while, so I don’t know,” Sheen concluded, “I know that originally the intention was that it would always be a one-off thing. Who knows? You never know in this business.”

You can still watch all six episodes of Good Omens on Amazon Prime, and look for The Beat’s full interview with Mr. Sheen sometime next week.
