Passenger’s star Michael Sheen and Doctor Who’s David Tennant have landed themselves lead roles in Neil Gaiman’s and Terry Pratchett’s TV series adaptation of fantasy novel Good Omens.

Good Omens was the first novel written by Gaiman alongside Pratchett before his death in 2015, now the story has its chance to be seen as a TV series which will consist of six one-hour long episodes. The series will exclusively launch on Amazon Prime video but viewers in the UK will also get the chance to view the series on the BBC.

Good Omens is set in 2018 on the brink of an apocalypse as humanity prepares for a final judgment. But Aziraphale (Sheen), a somewhat fussy angel, and Crowley (Tennant), a demon, aren’t enthusiastic about the end of the world, and can’t seem to find the Antichrist.

Good Omens

The book synopsis reads, “Armageddon only happens once, you know. They don’t let you go around again until you get it right.”

According to the Nice and Accurate Prophecies of Agnes Nutter, Witch – the world’s only totally reliable guide to the future, written in 1655, before she exploded – the world will end on a Saturday. Next Saturday, in fact, Just after tea…

People have been predicting the end of the world almost from its very beginning, so it’s only natural to be sceptical when a new date is set for Judgement Day. This time though, the armies of Good and Evil really do appear to be massing. The four Bikers of the Apocalypse are hitting the road. But both the angels and demons – well, one fast-living demon and a somewhat fussy angel – would quite like the Rapture not to happen. And someone seems to have misplaced the Antichrist…

Gaiman helped to adapt the story and will also serve as a showrunner on the series. Good Omens is produced by Amazon, BBC Studios and Narrativia.
