There's an important message that Emmy Award-winning Mad Men star Jon Hamm hopes the audience takes away after watching his latest project Good Omens, a novel-based epic six-part drama about an angel and a demon joining forces to stop an impending apocalypse.

The Amazon Prime Video series, based on the iconic 1990 novel by Neil Gaiman and late Terry Pratchett, stars Michael Sheen as angel Aziraphale, and David Tennant as demon Crowley.
