I Also Want To Add That Crowley, Before He Got His Bentley, Had To Use Black Horses And He Used To Fall

I also want to add that Crowley, before he got his Bentley, had to use black horses and he used to fall off of them because "he is not good with animals"

Some more Good Omens Book minutiae

There have already been some good posts highlighting trivia and changes between the book and show (a couple are here and here) so I thought I’d add in some more that might be useful and haven’t been overdone yet. Ones I think are most helpful are bolded!

Crowley can see in the dark (because he’s a demon, not because he’s a snake)

Crowley does eat (and notes that sleeping is enjoyable after a heavy meal), but on at least one canonical occasion Aziraphale takes Crowley’s portion of food for himself (angel food cake, to be exact, and he does it without needing to ask) so infer what you will about how we never see Crowley with food in the show

Crowley does read, or at the very least it mentions him attempting to calm his nerves by reading a novel

Aziraphale learned magic when he took a class in the 1870s taught by famous stage magician John Maskelyne

Aziraphale takes his tea without sugar

Crowley does not like to shapeshift, because he is afraid he’ll forget how to turn back 

It’s not terribly clear but somewhat implied that Nanny Ashtoreth and Brother Francis were NOT Crowley and Aziraphale (they reference a ‘team’ working for them) but that the two did exchange and compare notes on Warlock’s progress frequently. So thank Neil and Co. for the screenplay choices. Additionally, Brother Francis never actually did any real gardening, he just miracled everything to look perfect

When Warlock was 6 years old, nanny and gardener left and were replaced by two tutors, Mr. Harrison (evil) and Mr. Cortese (good)

Aziraphale will employ any means “short of actual physical violence” to discourage customers in his bookshop, including unpleasant damp odors and glowering looks to anyone who walks in

That clunky watch Crowley wears was custom-made to have the time in 20 world capitals as well as the time in Hell, which was always “Too Late”, and whose battery burned out years ago but he never noticed so it kept working

In 1653 Aziraphale added his own annotations to the proof sheets of a Bible published by Bilton & Scaggs Publishing (the same as who published the Nice and Accurate Prophecies), adding a bit about losing his flaming sword (basically the dialogue in the scene of the series where God confronts him at the gate in episode 3), and is now known as the Bugger Alle This Bible, one of a special collection of misprinted Bibles Aziraphale is proud to own

Aziraphale does watch films. This includes one documentary about gorillas making nests. He also makes an Exorcist reference.

For 6000 years Aziraphale thought dolphins were fish

Crowley watched Mary Poppins on TV at Christmas one year

Aziraphale buys his clothes, while Crowley manifests them

Anathema refers to Crowley and Aziraphale as “two consenting cycle repairmen” :)

Anathema’s bicycle is named Phaeton

Aziraphale’s bookshop is situated directly next to another bookshop called ‘Intimate Books’ and he occasionally gets confused customers that wrongly come into his shop

Anathema is British, not American, in the book

Adam has an older sister named Sarah

Aziraphale is the first angel to own a computer

After the non-Armageddon, Adam alters reality to send Warlock on a plane to America, because Adam thinks America is a cool and magical place and that Warlock deserves something good. (We do not find out if Warlock’s life improves, only that he liked England because it was ‘a good place to be an American’)

Crowley was so impressed by how diabolically mundane the warranty conditions for computers were that he sent a stack of them down to Hell’s ‘Immortal Souls’ agreement department with a memo saying ‘Learn, guys’

When Crowley trapped Hastur on his answering machine, he considered taking the tape and playing it in his car until it became Freddie Mercury, but he decided even that was taking it too far

While NOT show canon, in the book the combination to Crowley’s safe containing the holy water is 4-0-0-4, the year he “slithered onto this stupid, marvellous planet” (Neil has stated that the combination in the show is meaningless and was the default for the safe they bought)

In the book, it does NOT expressly say that Crowley destroys the plants he deems failures, just that he leaves and returns an hour later with an empty flowerpot

Crowley’s flat contains a bedroom, office, kitchen, lounge, and bathroom, each “forever clean and perfect” because he doesn’t really “live” there, as well as a fridge stocked with gourmet food that never spoils and the fridge isn’t even plugged in

Shadwell believes that Aziraphale is a Russian spy

Crowley and Aziraphale had both visited Shadwell’s apartment exactly once (and Aziraphale was rather disgusted by the state of the place)

In the book (as opposed to the show) Aziraphale is full aware (and nonplussed) that there’s only a 50/50 chance Heaven would win against Hell in Armageddon, and that it doesn’t matter for humans so much anyways because everyone will be killed horribly as civilian casualties during the war itself (a hilarious and very bitchy speech absolutely worth reading, when he possesses Marvin the TV preacher)

The road to Hell isn’t paved with good intentions, rather with frozen door-to-door salesmen, and young demons go ice-skating down it on weekends

Madame Tracy’s real name is Marjorie Potts

Aziraphale has “neat, copperplate” handwriting

Crowley is an optimist

It turns out, Hastur’s murder of the telephone salespeople prevented a Crowley-esque domino effect of thousands of people getting angry from the calls and passing that anger on and on, thus actually spreading a wave of low-level goodness across London

In the book, the M25 wasn’t actually on fire, but rather an inexplicable glowing combination of “pain and dark light” called infra-black, and was both 700 degrees Celsius and -140 at the same time. The Bentley spontaneously combusted when crossing it.

When Crowley meets Aziraphale-as-Tracy, he does say ‘Is that you? Nice dress’ but the TV version added the ‘It suits you.’ However in the book he also says ‘Aren’t you going to introduce me to your new body?’ :)))

When Adam acknowledges Crowley at the airbase, Crowley feels true terror for the first time in his life, because while Hell could make you cease to exist, the Antichrist could make it so you never existed in the first place

When Aziraphale makes the soldier disappear, he actually was transported back to his childhood home in America where his family lives

In the book, to get them both home from Tadfield Crowley steals a Jeep from the airbase

Crowley and Aziraphale are deadass just referred to as ‘the couple with the bottle [of wine]’ one time

There is no body swap scene at the end, because there didn’t need to be; in the book, the stakes of Aziraphale and Crowley’s Arrangement were not nearly as high. A big deal was never made of it, as they were too unimportant to warrant the attention of their superiors. Retribution never came. While they could get in trouble (and Crowley was threatened many times) for defying orders concerning the Apocalypse, little mention was made of their friendship being a crime. Thus, they never had any real reason to deny being friends, and were much more comfortable with their loyalties and each other. This lack of tension marks the biggest divergence between the series and book, and creates a starkly different (and interesting!) dynamic for the characters in the show.

Just me but I get the distinct sense that book Aziraphale and Crowley are already an old bickering married couple and this explains the distinct lack of pining lmao.

Anyway, I hope these were enjoyable or helpful!
