Everyone is desperate to know the fourth season Black Mirror release date, but although we don't have it quite yet, what we do have is a trailer for one of the six episodes of the season – Arkangel. 

Directed by actor Jodie Foster (perhaps best known for her role in The Silence of the Lambs, and more recently for directing episodes of House of Cards and Orange is the New Black), the trailer seems to point towards the unnerving trend of helicopter parenting.

A young, blonde child (Aniya Hodge) goes briefly missing and her petrified mother, played by Rosemarie DeWitt, then takes her to have some kind of tech implanted in her head with a long, dangerous-looking needle.

Going by the dystopian satire standards of previous Black Mirror episodes, it seems likely the tech will let mum see out of her child's eyes, and something will go badly wrong.

There's also a middle-aged looking man saying he's 2000 years old, so we're sure that the general concept of ageing will come into the episode somehow.

As Charlie Brooker said to Dazed about his creative process last year: “Often, it’s an idea that makes me laugh, or something that, if played straight, would be really disturbing and awful. Generally, the basic rule is: some horrible logic spirals out of control.”
