Get your first look at David Tennant and Michael Sheen in Good Omens

Crowley and Aziraphale are in the building. The Twitter account of late Good Omens co-author Terry Pratchett shared the first image of David Tennant and Michael Sheen in costume as the otherworldly pair for the upcoming Amazon series, showing the two serving looks as the popular literary characters. "Terry would be beyond proud today," the picture was captioned. "Thank you David and Michael."

Good Omens, based on the novel by Pratchett and American Gods scribe Neil Gaiman, is a dark comedy about the preparations for the quickly impending apocalypse. Tennant's Crowley, a demon (if you couldn't already tell by his all black ensemble) and Sheen's Aziraphale, an angel, are both happy with their lives on earth, so they decided to team up to stop the coming doom. 

The rest of the cast for the series includes Harry Potter actress Miranda Richardson as a psychic who teams up with the pair to save the world; Fresh Meat's Jack Whitehall as an unfulfilled wages clerk turned witch-hunter; and Better Call Saul's Michael McKean as the leader of a witching finding army. Adria Arjona, Nina Sosanya, Ned Dennehy, and Ariyon Bakare also star.

The six-episode series is set to hit Amazon in 2018. While we wait, see some of the shows you have to look forward to this year.
