Michael Sheen and David Tennant are set to star in a new TV series based on Neil Gaiman’s first novel, Good Omens.

The series is being made by Amazon, but will be shown on the BBC in the UK.

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

Sheen will play the role of Aziraphale, while Tennant will play Crowley. The series will consist of six one-hour episodes.

“I first read ‘Good Omens’ as a teenager and it’s been one of my favourite stories ever since,” Sheen said in a statement to Variety.

“To be part of the team entrusted with bringing it alive on screen is a bit of a dream come true to be honest. To work alongside Neil, who I think is one of the greatest storytellers of all time, is incredibly exciting. And, just like the rest of the world, I’m a huge fan of David’s so I relish trying to save it with him.”
