Exclusive: Get a sneak peek at two new 'Black Mirror' episodes

In case you've never seen Black Mirror — and really, you should just fix that now — the British anthology series puts a futuristic Twilight Zone-style spin on modern society and technology, usually in very creepy, a-little-too-close-to-real-life fashion.

Before the third season debuts on Netflix for streaming Oct. 21, we've got an exclusive sneak peek at two of the six new episodes, each starring a second-generation Hollywood star.

Bryce Dallas Howard, daughter of Ron Howard, toplines "Nosedive" as a woman living in a culture where social-media "likes" are everybody's top priority — the episode is "a satire on acceptance and the image of ourselves we like to portray and project to others," explains writer and creator Charlier Brooker.

And in "Playtest," a traveling thrill-seeker played by Wyatt Russell, son of Kurt Russell and Goldie Hawn, finds a virtual-reality game gets way too real in what Brooker calls "a techno-horror romp. I wanted to do one (episode) that was deliciously dark but also had elements of fun to it."
