'Black Mirror' Season 4: How each episode matches up with reality

It's hard to distinguish what's real and what's not in the latest series trailer

Throughout it's past three seasons, the allusions to news events and the threat of technology have run rampant throughout Netflix series Black Mirror.

However Friday's New Year's-themed promotional video in honour of the start of series four makes it hard to differentiate between reality and sci-fi fantasy.

From video clips of Sean Spicer to promoting a dating app that matches you with your "haters", the two-minute trailer walks viewers through moments that happened in 2017 - and moments that could have happened.

It appears that this season will also include riots, futuristic contact lenses, the focus on fake news, people potentially voting a cartoon character into office and wanting to kill each other.

It's okay if you're not sure which is which, since Black Mirror just premiered six new episodes on Netflix to clear up the confusion.

Since 2011, the modern-day Twilight Zone-esque show has served as a cautionary tale for humanity, politics and technological dependency.

Creator Charlie Brooker spoke to The Independent about how the news doesn't determine the stories told on Black Mirror.

"What we don't tend to do is look at the news and say, 'What's the Black Mirror take on Brexit?' he said.

"We don't look at technology pages either. It comes out of...you know that you've got a good idea when you get excited about the ramifications of the concept."

From Brooker's interview, it appeared some of his parallels and predictions mistakenly became reality.

The fourth series includes six female-led episodes featuring directors Jodie Foster, David Slade and John Hillcoat.

The episodes star Andrea Riseborough, Cristin Milotti, Rosemarie DeWitt, Maxine Peak, Georgina Campbell and Letitia Wright.

You can stream them all now on Netflix.
