“So for you, for me, for all of us. FOR PEOPLE NOT YET BORN. This is what Jon Hamm looks like as the Angel Gabriel in the upcoming TV series of GOOD OMENS. A thing of beauty, and a joy forever”.

The TV adaptation of Neil Gaiman and Terry Pratchett’s novel is currently in production on the six-episode series which is due to air in 200 countries worldwide on Amazon Prime in 2019 and will be seen on BBC later in the same year.

Jon Hamm shared his thoughts on the story when his casting was announced: “I read Good Omens almost twenty years ago. I thought it was one of the funniest, coolest books I’d ever read. It was also, obviously, unfilmable. Two months ago Neil sent me the scripts, and I knew I had to be in it.”

Also on the cast are David Tennant and Michael Sheen, The BBC/Amazon co-production will see Tennant play the demon Crowley, while Sheen is the angel Aziraphale in the fantasy drama which 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.

The series will be helmed by director/executive producer Douglas Mackinnon, whose credits include Knightfall, Dirk Gently, Doctor Who, Outlander and the standalone Victorian episode of Sherlock: The Abominable Bride.
