Refitted for Sequel: Inverted. In an interview with GQ , Neil Gaiman said that certain elements — like the expanded roles of some of the angels like Gabriel, Uriel and Sandalphon — were ideas that he took from a sequel to the book that he and Terry Pratchett had planned but never written. Played straight with the announcement of a second series, which Gaiman has indicated will use material from said unwritten sequel. Neil Gaiman and Michael Sheen have both stated that when they began discussing working on the show they both assumed Sheen would play Crowley. Once Gaiman actually started to write the scripts he realised that Sheen would be better suited to the role of Aziraphale. Episode six gives us a glimpse of how Sheen might have played Crowley. Nina Sosanya as well. Her agent was very doubtful about asking her to play a Satanist nun, and she immediately said "Oh, Sister Mary Loquacious!" Dueling Shows: 2019's Miracle Workers (Season One) had a similar concept about two angels trying to stop God from ending the world, with heavy emphasis on comedy. Both shows were adapted from novels, although Good Omens predates What in God's Name by 22 years. Jon Hamm was also a fan of the book and jumped at the chance to play the expanded role of Archangel Gabriel.

Crowley: Gravity. It’s a thing that happens when objects are pulled together. In this case, they’re all pulled downwards because the Earth is the largest thing around.Content Leak: On 12 May, 2023, Neil Gaiman posted to social media to warn fans of a content leak regarding season two, advising them to avoid spoilers until the series was released in July. Self-Adaptation: Neil Gaiman, who was one of the co-authors of the original book, served as the showrunner and main writer for this series. Queer Character, Queer Actor: In series 2 episode 5, Mutt's Spouse is a non-binary character played by non-binary performer Andrew O'Neill.

The Other Darrin: Beelzebub is played by Anna Maxwell Martin in Season 1 and by Shelley Conn in Season 2, as Martin was too busy to reprise the role. This is joked about in-universe; Crowley actually asks Beelzebub if they're wearing a new face, only for them to brush it off and say they've had it for ages, while when Gabriel questions them about it, Beelzebub simply says they got bored of having the same face for centuries. Elsbeth makes choices Aziraphale can't understand because she doesn't have the opportunities he seems to think are universal. Like Game of Thrones, the title sequence only lists the main cast members who actually appear in the episode as opposed to the entire main cast. So far, so good, but the third episode's title sequence is placed about a half hour into the episode, and lists Mark Gatiss, Steve Pemberton, and Reece Shearsmith despite all three appearing in minor cameo roles that are over by the time the title sequence begins. The relationship between Aziraphale and Crowley has been written as a love story from the Garden of Eden onwards.Real-Life Relative: David Tennant's father-in-law Peter Davison appears in "The Clue" as Job. Ty Tennant, David's oldest child and Peter's grandson, plays Job's oldest son in the same episode. Crowley: Uh, honestly, I don’t remember. Seemed like a good idea when we were all talking about it. So things will stay where you put them? Not just drift off? Crowley's answering machine plays way too big a role to be jettisoned completely, so it's referenced as an antique he's hanging onto, and his cell phone also plays a part in the plot point. War's introduction originally more closely followed the one in the book. It was even shot. However, people found it confusing, necessitating that it be rewritten and reshot.
