With all the divine goings-on throughout Good Omens, adapting the novel of the same name by Neil Gaiman and Terry Pratchett, one of the characters who steps up to save existence is the unassuming angel Aziraphale. Played by Michael Sheen, Aziraphale hides the archangel Gabriel in his bookshop when the holy authority figure comes to Earth having completely forgotten his identity. This places Aziraphale and his demonic best friend Crowley, played by David Tennant, on another adventure between the forces of Heaven and Hell as they scramble to avert another theological catastrophe.
