David Tennant and Michael Sheen will have the company of another angel in the coming mini-series Good Omens.” The two are going to be joined by Jon Hamm to play the role of the archangel Gabriel, God’s primary messenger.

BBC’s television adaptation of Terry Pratchett and Neil Gaiman’s collaboration novel with the same title is now in production. In fact, the 46-year-old actor himself admitted that he is a big fan of the book, and he once feared that it will never be seen on television.

Hamm perfect fit to play as Gabriel

“I read ‘Good Omens’ almost 20 years ago,” Jon Hamm said (via Variety).

The “Baby Driver” star described the book as “one of the funniest and coolest books” he had ever read. “It was also, obviously, unfilmable,” he added. When the novel’s author Neil Gaiman sent him the television show’s script, he perfectly knew that he has to be in it. Hamm’s character as Gabriel only has a brief role in the book, but the novelist is said to be working out how to make his stay in the series longer.

“He is everything that Aziraphale isn’t,” Gaiman said. So, he is going to expand Gabriel’s story in the television show. He even said that they were fortunate enough to have Jon Hamm around. With his charismatic looks, well-dressed, and tall height, he is the best actor to play the archangel’s role.

The novel’s author even bragged that he has all of Gabriel’s traits that he doesn’t need to act. It was also another point that Hamm was an avid fan of the novel and a very good actor.

Neil Gaiman also said that when they already finished writing “Good Omens” dawn of prehistory, he and Terry Pratchett decided to start writing a sequel.

“There would have been a lot of angels in the sequel,” he said (via Gizmodo).

The novel’s television adaptation

Neil Gaiman proudly said that he and Terry Pratchett were happy to introduce the fictional angels they made.

The book was first published in 1990 and was snapped up by Hollywood, but the movie was never made. So, 30 years after, he stated that he started writing “Good Omens” to be adapted to a television show.

From there, he perfectly knew that their angels “would have to be in there.”

Aside from Jon Hamm, Michael Sheen and David Tennant are going to play the titular roles as the angel Aziraphale and the evil Crowley. Jack Whitehall also joins the series as Newton Pulsifer, Michael McKean as Shadwell, Miranda Richardson as Madame Tracy, and Adria Arjona as Anathema.

“Good Omens” is set to be released on the Amazon Prime Video streaming in 2019 and on BBC Two.
