'Good Omens' adaptation finds its angel and demon in Michael Sheen and David Tennant

Actors Michael Sheen and David Tennant have been cast in the lead roles in the Amazon series adaptation of Good Omens.

The series is based on Neil Gaiman and Terry Pratchett's novel of the same name, reported Variety.

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

Sheen will play the role of Aziraphale, while Tennant will play Crowley. It 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. 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," Sheen said in a statement.
