Query: Did Terry Prachett also help write Good Omens?
Pratchett's first two adult novels, The Dark Side of the Sun (1976) and Strata (1981), were both science-fiction, the latter taking place partly on a disc-shaped world. Subsequent to these, Pratchett mostly concentrated on his Discworld series and novels for children, with two exceptions: Good Omens (1990), a collaboration with Neil Gaiman (which was nominated for both Locus and World Fantasy Awards in 1991[174]), a humorous story about the Apocalypse set on Earth, and Nation (2008), a book for young adults.
Omina could be good or bad. Unlike prodigies, bad omina were never expiated by public rites but could be reinterpreted, redirected or otherwise averted. Some time around 282 BC, a diplomatic insult formally "accepted as omen" was turned against Tarentum and helped justify its conquest. A thunderclap cost Marcellus his very brief consulship (215 BC): thereafter he traveled in an enclosed litter when on important business, to avoided sight of possible bad omens that might affect his plans. Bad omens could be more actively dealt with, by countersigns or spoken formulae. Before his campaign against Perseus of Macedon, the consul L Aemilius Paullus was said to have heard of the death of Perseus, his daughter's puppy. He interpreted this as a favourable omen and defeated King Perseus at the Battle of Pydna (168 BC).
Terry Pratchett said:
I think this is an honest account of the process of writing "Good Omens". It was fairly easy to keep track of because of the way we sent discs to one another, and because I was Keeper of the Official Master Copy I can say that I wrote a bit over two thirds of "Good Omens". However, we were on the phone to each other every day, at least once. If you have an idea during a brainstorming session with another guy, whose idea is it? One guy goes and writes 2,000 words after thirty minutes on the phone, what exactly is the process that's happening? I did most of the physical writing because:
Initially, I did most of Adam and the Them and Neil did most of the Four Horsemen, and everything else kind of got done by whoever – by the end, large sections were being done by a composite creature called Terryandneil, whoever was actually hitting the keys. By agreement, I am allowed to say that Agnes Nutter, her life and death, was completely and utterly mine. And Neil proudly claims responsibility for the maggots. Neil's had a major influence on the opening scenes, me on the ending. In the end, it was this book done by two guys, who shared the money equally and did it for fun and wouldn't do it again for a big clock.
In 2014 it was announced that Serafinowicz would play the role of Crowley in the BBC Radio 4 adaption of Terry Pratchett and Neil Gaiman's novel "Good Omens".
In February 2011, it was reported that a television adaptation may be produced, with Terry Jones and Gavin Scott being "in talks" to write the series.
On 5 September 2014, it was confirmed that the BBC would produce a radio adaptation of the novel, to be broadcast on BBC Radio 4, starting 22 December of that year. Mark Heap and Peter Serafinowicz led the cast, which also included Louise Brealey, Phil Davis, Mark Benton, Colin Morgan, Paterson Joseph, Josie Lawrence, Jim Norton, Adam Thomas Wright and Hollie Burgess. Neil Gaiman and Terry Pratchett had cameo roles as a pair of traffic cops called "Neil" and "Terry". The series was broadcast in six episodes starting in April 2015.
Death in BBC Radio 4 production of Good Omens by Terry Pratchett and Neil Gaiman, December 2014.
An "oionos" (omen) was defined in antiquity as the carnivorous vulture, especially a prophetic bird. By careful observation of the bird’s cries and the way or direction it flew, the augurs attempted to predict the future. They also saw lightning or thunder as omens, sent from Zeus, and observed the direction in which they saw or heard them. Omens represented the divine will and the decisions of the gods, their positioning opposite human endeavors, and were aimed at being understood by sensitive receivers of the time, who brought the divine charisma to become intermediaries, channels between the world of gods and humans. Even since Homeric times, the Greeks paid special attention to these signs: when they saw vultures from the left, another symbol of Zeus, they considered it a bad omen. The cry of a heron or a lightning to the right marked positive and promising omen. In the Greek territory, seers also judged good and bad omens from the unwillingness or willingness of a victim to approach the altar and by the state of its offal when slaughtered.
In the Terry Pratchett and Neil Gaiman novel Good Omens the River Uck plays a small, but important scene in the narrative.
Neil Gaiman has said: 
We were both living in England when we wrote it. At an educated guess, although neither of us ever counted, Terry probably wrote around 60,000 "raw" and I wrote 45,000 "raw" words of "Good Omens", with, on the whole, Terry taking more of the plot with Adam and the Them in, and me doing more of the stuff that was slightly more tangential to the story, except that broke down pretty quickly and when we got towards the end we swapped characters so that we'd both written everyone by the time it was done, but then we also rewrote and footnoted each other's bits as we went along, and rolled up our sleeves to take the first draft to the second (quite a lot of words), and, by the end of it, neither of us was entirely certain who had written what. It was indeed plotted in long daily phone calls, and we would post floppy disks (and this was back in 1988 when floppy disks really were pretty darn floppy) back and forth.
In April 2016, Gaiman announced that he was writing the scripts for a six-part television series as the result of a request from Pratchett, shortly before his death. In January 2017, further details emerged. Amazon.com announced that Gaiman will adapt "Good Omens" into a "comedic apocalyptic" miniseries, set to be released on Prime Video in 2019. The adaption will be a six-part limited comedy series for Amazon and the BBC, and Gaiman will also serve as showrunner. On 14 August 2017 Michael Sheen and David Tennant were announced as having been cast in the lead roles of Aziraphale and Crowley respectively in the forthcoming miniseries.
A film, directed by Terry Gilliam, was planned. As of 2002 Gilliam still hoped to make the film with its already completed script, but by 2006 it seemed to have come to nothing. Funding was slow to appear and Gilliam moved on to other projects. There was a rumour that Johnny Depp was originally cast as Crowley and Robin Williams as Aziraphale. However Gaiman has said on his website, "Well, Robin's worked with Terry Gilliam before as well, of course, most famously in "The Fisher King". But I have no idea about "Good Omens" casting (except for Shadwell. Terry told me who he wanted to play Shadwell. I immediately forgot the man's name, although I can assure you that it wasn't Robin Williams)." According to an interview in May 2006 at "The Guardian" Hay Festival, Gilliam was still hoping to go ahead with the film.
In 2014, a six-part adaption of Good Omens aired on BBC Radio 4, and featured cameos by both Terry Pratchett and Neil Gaiman.[202]
The tour of "Blithe Spirit", starring (newly titled) Dame Angela Lansbury, then went to London's West End in early 2014. This was accompanied by an appearance at a special cabaret (organised by co-star Janie Dee) at the Cafe de Paris, where Simon sang "Mad Dogs and Englishmen". When the West End performance ended, in June, he immediately went into the role of 'Emperor Joseph II' in "Amadeus", starring Rupert Everett. This was followed by BBC Radio appearances in Neil Gaiman and Terry Prachett's "Good Omens", directed by Dirk Maggs and "Doctor Who" with Tom Baker. 
After writing Good Omens, Pratchett began to work with Larry Niven on a book that would become Rainbow Mars; Niven eventually completed the book on his own, but states in the afterword that a number of Pratchett's ideas remained in the finished version.
In a collaboration with author Terry Pratchett, best known for his series of "Discworld" novels, Gaiman's first novel "Good Omens" was published in 1990. In 2011 Pratchett said that while the entire novel was a collaborative effort and most of the ideas could be credited to both of them, Pratchett did a larger portion of writing and editing if for no other reason than Gaiman's scheduled involvement with "Sandman".
The novel "Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch" by Neil Gaiman and Terry Pratchett satirizes the apocalypse and several events of the film, including the baby swap.
Set in 2018, the series will follow the demon Crowley (Tennant) and the angel Aziraphale (Sheen), who, being accustomed to life on Earth, seek to prevent the coming of the antichrist and with it the final battle between Heaven and Hell.Pratchett and Gaiman had planned to adapt "Good Omens" as a movie for years, with various directors and writers attached to the project at various times. In 2011, a television series, written by Terry Jones and Gavin Scott, was first reported to be in the works but no further plans were announced. After Pratchett's death, Gaiman refused to ever consider working on the adaptation alone but changed his mind when he received a letter from Pratchett, written to be sent after his death, urging him to finish the project.
The methods used by commercial collaborative writers vary tremendously. When beginning writing the short story 'the toy mill' Karl Schroeder and David Nickle began by writing alternating sentences, whereas when English authors Terry Pratchett and Neil Gaiman wrote "Good Omens" they largely wrote separate plotlines and then collaborated much more heavily when revising the manuscript.
In December 2014, Lawrence played the role of Agnes Nutter in an adaptation of Terry Pratchett and Neil Gaiman's book "Good Omens" for BBC Radio 4.
From 2002 to 2006, Gilliam tried to get funding for an adaptation of "Good Omens", by Terry Pratchett and Neil Gaiman, with Robin Williams and Johnny Depp rumored as possible stars, but movie studios found the apocalyptic theme unacceptable in the wake of the 9/11 terror attacks, and funding never materialized.
Comets also have been considered both good and bad omens. Halley's Comet was a "bad omen" for King Harold II of England but a "good omen" for William the Conqueror.
Good Omens is an upcoming television serial based on the 1990 novel "Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch" by Terry Pratchett and Neil Gaiman. A co-production between Amazon Prime and BBC Two, the six-part series was directed by Douglas Mackinnon and written by Gaiman, who served as showrunner. The series stars an ensemble cast featuring David Tennant, Michael Sheen, Jon Hamm, Anna Maxwell Martin, Josie Lawrence, Adria Arjona, Michael McKean, Jack Whitehall, Miranda Richardson and Nick Offerman.
In August 2012, Rhianna Pratchett, Terry and Lyn's daughter, announced an establishment of a new production company, Narrativia, with plans to, among other projects, produce a TV film based on "Good Omens".
In 2017 Hamm joined the BBC and Amazon's television adaptation of Terry Pratchett and Neil Gaiman's "Good Omens" as the Archangel Gabriel.
