Neil Gaiman's Good Omens is set for a Season 3 renewal by Amazon and BBC. Main cast members, including Michael Sheen and David Tennant, are expected to return. However, Douglas Mackinnon, executive producer and co-showrunner for the initial two seasons, has confirmed his exit from the show. Despite Mackinnon's departure, Season 3 appears to be on the horizon, especially given the success of Season 2. Neil Gaiman has hinted that the upcoming season will be inspired by the unfinished sequel to the original Good Omens novel and has also clarified there won't be a fourth season.
