How Neil Gaiman Shared Good Omens 2's 'Delicious' Plot [Exclusive]

When "Good Omens" dropped on Prime Video in 2019, the surprisingly cozy story about an angel (Michael Sheen) and a demon (David Tennant) working together to avert the apocalypse became an antidote to the brooding prestige TV so many of us had grown numb to. In fact, it was such a pleasant story that, after reaching its conclusion as presented in Neil Gaiman and Terry Pratchett's classic book of the same name, Gaiman and co. decided they didn't want it to end just yet.

That's great, because neither did the fans. News of "Good Omens" returning for a second season was met with excitement. Each new detail that's dropped, from the poster featuring the odd couples' wings coming together to make a black-and-white heart shape to the trailer, which features an amnesiac Gabriel (Jon Hamm), has been intensely scrutinized and squealed over. Still, the question remains: how did Gaiman decide on the story for season 2, and when did the show's costars learn they'd be back for a second round of comedy, chemistry, and chaos?

/Film's Vanessa Armstrong got the answers in an interview with Sheen and Tennant, which it should be noted took place before the ongoing SAG-AFTRA strike began. When asked about how and when Gaiman, who created and showruns the series, pitched the second season, Tennant revealed that "it gradually came into focus over a couple of years, probably." The actor notes that "the initial idea that there might be more story to tell" might have actually "had its genesis way, way back as a sort of fantasy idea, really, where we were shooting [season] 1." Like many a TV show these days, the show was initially marketed as a limited series, but that didn't last; it was officially renewed in 2021, two years after it aired.

While it sounds like Gaiman and the cast perhaps daydreamed about keeping the fun going with another season during production on the first, Tennant says the pieces still didn't come together until after it aired. "Then [season] 1 came out, and I think from that point, there was a slow realization that actually there might be more to come," he told /Film. "Neil was clearly excited at the idea, and I think Amazon were keen to do it." Some limited series clearly have aspirations for a sophomore season, but Tennant insists that he and Sheen "always thought it was a one-off," having signed contracts for one season and only been pitched on one season. When they got the go-ahead for another, though, he explained, "Michael and I were thrilled that we would get to return to [these] characters."

"When we started off on that journey, there was never a sense to go further, but what a treat that it was going to," Tennant explained. It took a long time for the full season 2 picture to come into focus: "I think Neil would drop us little nuggets down the months and years, really," he told /Film. Sheen, meanwhile, says he has "no memory whatsoever' of how Gaiman told him about the plans for Aziraphale in season 2. He did, however, have an inkling based on conversations Gaiman had described having with Pratchett about a continuation of the story before the author's death in 2015. "I know what we wanted to explore," Sheen said, "and I always remember what he was aiming to get to by the end of the second series, because of ideas that he and Terry had talked about with where the story might go."

Sheen says he thinks the first thing Gaiman told him about season 2 involved "the idea of Gabriel coming into their lives again in a very unexpected way, and then that eventually building to the point that they get to at the end of this series." Tennant, meanwhile, remembers being in Romania on a shoot for "Around The World in 80 Days" when Gaiman shared the first scene of season 2 with him and Sheen over Zoom. "Neil read us the first scene, the opening scene, which is, if you've seen it, you'll know we meet a very youthful Crowley and Aziraphale, very much way back at the beginning of time." Tennant says Gaiman "then gave us a quick sketch of what the rest of the series was going to be." Though both actors are understandably trying to keep mum about the ending of season 2, they note that Gaiman told them what it would be early on.

"That was all worked out, and it just felt delicious, really," Tennant says after recalling the Zoom meeting. "I mean from that moment on, it just felt like it was always meant to be. It felt like it was such a perfectly formed idea. I think it's fair to say that Michael and I didn't need much persuading." That's great to hear, because we certainly didn't need persuading to sign up for a season 2, either. The new "Good Omens" adventure begins on Prime Video on July 28, 2023.
