My theory is that we used to have several personalities, and now we're encouraged to have one online.

My continuum? Blimey! For me,Black Mirror is all part of the whole.

"Be Right Back," in which Hayley Atwell brings Domhnall Gleeson back from the dead using his social-media profile, sprang out of an unrelated conversation. Other stories you thrash away at for weeks and weeks.

[Worshipping God] is like fellating someone who intermittently stubs fags out on your head for no good reason. And we all know how unsatisfying that can be.

I could worry that I'm going to bleed to death, you know, from cutting my finger on a sandwich packet, you know, if I sort of open a sandwich.

As long as we've still got crazy "what if" ideas, we can continue [Black Mirror]. It's outpacing reality that's probably the challenge.

Overall, looking at the stories [Black Mirror], almost every story we've ever done is concerned with authenticity or reality in some way.
