Amazon’s ‘Good Omens’ Lands Michael Sheen and David Tennant

The news that Amazon was going to be producing a miniseries adaptation of Terry Pratchett and Neil Gaiman’s beloved comic fantasy novel Good Omens was wonderful enough in itself. But now the production has taken things even further with some truly heavenly casting.

Variety reports that Good Omens has signed on Michael Sheen and David Tennant to play the two lead roles, the angel Aziraphale and the demon Crowley, respectively. Set in 2018, on the eve of an impending apocalypse, Good Omens follows the friendship between Aziraphale and Crowley as they attempt to track down the antichrist and prevent the end of the world (they’ve decided they like it here).

Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch was first published in 1990, a collaboration between Terry Pratchett, best known for his Discworld books, and Neil Gaiman, who went on to become a juggernaut of the fantasy genre with works like American Gods and his Sandman comic series. Gaiman wrote the scripts for this Amazon version, and is serving as showrunner.

Sheen recently wrapped up a four-season run on Showtime’s Masters of Sex, where he played sex researcher William Masters, opposite Lizzy Caplan as Virginia Johnson. Tennant is best known for his role as the Tenth Doctor on Doctor Who, as well as acclaimed turns in Broadchurch and Netflix’s Jessica Jones. That latter role let him embrace his villainous side, so it should be interesting to see what he brings to his performance as the demon Crowley.

In a statement to Variety, Sheen said:

I first read Good Omens as a teenager and it’s been one of my favorite 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.

There’s no official release date for Good Omens yet, but Prime subscribers can expect to see it in their catalog sometime in 2018. In the meantime, there’s always American Gods
