Subscribers’ worst nightmare is Black Mirror S6’s first episode

“Black Mirror” season six premiered Wednesday on Netflix with a disturbing trailer. The streamer debuts the series on June 15.

The trailer begins with a glimpse of the first episode, which, like all “Black Mirror” episodes, is terrifying.

Episode one, “Joan is Awful,” features “Streamberry,” a Netflix clone that plays the “ta-dum” sound for three seconds when users log in. The episode features Annie Murphy from “Schitt’s Creek” as Joan. Joan learns that Salma Hayek plays her in a streaming service TV drama.

The new trailer shows more clips from the highly anticipated five-episode season. Michael Cera, Rob Delaney, Aaron Paul, Josh Hartnett, Rory Culkin, Kate Mara, Zazie Beetz, and Himesh Patel also star.
