At the end of the trailer, a release date for the series is finally revealed.
Netflix previously released teasers for the individual episodes, but this trailer gives us glimpses of everything we can look forward to this season and, as expected, it looks fairly bleak.
"U.S.S. Callister" is the fourth episode of the fourth season of "Black Mirror", and will be seen sometime in 2018.
"Crocodile", directed by The Road's John Hillcoat, takes place in Iceland, in a future where memories are no longer private. Without questioning it, technology has transformed all aspects of our lives; in every home; on every desk; in every palm - a plasma screen; a monitor; a Smartphone - a Black Mirror reflection.
"Arkangel" is parenting à la Black Mirror, wherein a kid wandering off a playground is clear proof that "the key to good parenting is control", which means punching needles directly into children's temples. Directed by Jodie Foster. Starring Georgina Campbell, Joe Cole and George Blagden, "Hang the DJ" is directed by Tim Van Patten. The episode, directed by Colm McCarthy, stars Douglas Hodge, Letitia Wright, and Babs Olusanmokun. The black-and-white episode, "Metalhead", is a fast-paced, primal episode with a terrifying robot dog. Director David Slade tells the story completely in black and white.
Starring Jesse Plemons, Cristin Milioti, Jimmi Simpson, and Michaela Coel, this marks Black Mirror's first-ever journey into space.
Black Mirror has gained a reputation as a relentless science-fiction series, becoming one of Netflix's flagship genre shows and a source of brutal self-examination that explores how we use and depend on technology.
