Olivia Colman is joining the sixth season of Hulu’s “Only Murders in the Building” as a guest star. The casting news is announced in a video shared on the show’s social media, featuring series leads and other cast members.

Across outlet reports, the details are consistent: Colman’s appearance is tied to Season 6, and the announcement comes through posts that include Selena Gomez, Meryl Streep and Martin Short. Deadline and Variety both describe the season as moving beyond its usual setting, with one framing it as taking place “across the pond” and another specifying that Season 6 is London-set. Belfast Telegraph also reports on Colman joining the next series of the comedy-mystery show.

While the outlets differ slightly in how they describe the season’s location—using broader wording in one case versus explicitly naming London in another—they agree that Colman is a new guest addition revealed through the show’s official promotional materials. No additional plot specifics about Colman’s role are included in the provided summaries.
