In Amazon’s new miniseries, Good Omens, an angel and a demon come together to stave off the end of the world. Now, it looks like that unlikely duo is going to be getting a little help from a “mad man.” Actor Jon Hamm has joined the cast of the show in the role of Archangel Gabriel.
Former Doctor Who star David Tennant stars alongside versatile actor Micheal Sheen as Crowley and Aziraphale, respectively.
Acclaimed writers Neil Gaiman and Terry Pratchett wrote the book the series is based on in 1990, and Gaiman will serve as showrunner after having written all six episodes.
Pratchett and Gaiman had plans for a sequel called 668 — The Neighbour of the Beast, but after Gaiman’s move to the United States and Pratchett’s death in 2015, it never came to fruition.
According to Gaiman, Hamm’s role as Gabriel actually stems from those sequel plans, as the character has only a minor role in the original novel.
In a press release, Gaiman revealed that the sequel would have featured a lot of other angels, so when he began writing the Good Omens miniseries, he says, “one thing I knew was that our angels would have to be in there.”
Hamm, of course, first came to the public’s attention as the womanizing ad executive Don Draper for seven seasons on AMC’s Mad Men.
He’s stayed busy since then, though, with a role in this summer’s surprise hit Baby Driver and several television appearances, including a recurring role on the Netflix series Unbreakable Kimmy Schmidt.
Michael McKean, Jack Whitehall, Adria Arjona, Nina Sosanya, Ned Dennehy, and Ariyon Bakare are also slated to appear in the miniseries, which is now filming in London. The Good Omens adaptation will arrive as an Amazon Prime exclusive in 2019 before it’s broadcast on television in the UK on BBC2 later that year.
