Michael Sheen and David Tennant star in this six-part miniseries based on the fantasy novel by Terry Pratchett and Neil Gaiman. Angel Aziraphale (Sheen) and demon Crowley (Tennant) are Heaven and Hell's respective representatives on Earth and, having been on the planet for over 6,000 years, have become rather accustomed to life on the planet. However, when the eleventh birthday of the Antichrist (Sam Taylor Buck) signals the beginning of the prophesised Armageddon, Aziraphale and Crowley must find a way to avert the impending catastrophe. The episodes are: 'In the Beginning', 'The Book', 'Hard Times', 'Saturday Morning Funtime', 'The Doomsday Option' and 'The Very Last Day of the Rest of Their Lives'.
