If you're anything like us, you've torn into this new series of Black Mirror with wild abandon, ignoring your family, your friends, your need to eat and sleep, in a desperate bid to watch it all as fast as possible.
The only thing that might be spoiling your viewing experience is that because Black Mirror doesn't focus on big-name stars (save for a few), it's one of those shows where you spend the entire episode going "WHERE have I seen that person before?" then pausing it to frantically IMDb the actor.
To make things easier for you, we've gone through and pulled out all the actors and actresses you're likely to do this with and given you their brief history.
"Arkangel" – Rosemarie DeWitt
In "Arkangel", Rosemarie DeWitt plays mother to Sarah, the 3-year-old girl who momentarily goes missing, leaving her mother in a panic over how to keep her safe.
Where you've seen her before
Rosemarie has a serious acting CV so you've probably seen her in all sorts of things. She was in La La Land as Laura, Mad Men as Midge (a free-willed illustrator who had an affair with Don), Rachel Getting Married as Rachel and Your Sister's Sister.
She is also IRL married to Ron "Jack Berger, Mr Post-It" Livingston.
"USS Callister" – Jesse Plemons
Jesse plays the dashing and ridiculous Captain Daley in this Star Trek -esque film.
Where you've seen him before
Jesse has been quietly chalking up serious acting points for a while now. From playing the hapless Landry in Friday Night Lights to appearing as Todd in Breaking Bad and Ed Blumquist in Fargo the TV series. He's also had parts in Bridge of Spies, American Made and Black Mass.
Jesse is engaged to Kirsten Dunst and the two are expecting a baby.
"USS Callister" – Cristin Milioti
Cristin appears as Lieutenant Cole.
Where you've seen her before
Cristin plays Teresa Petrillo, the long-suffering first wife of Jordan Belfort in The Wolf of Wall Street and she's also in a memorable episode of 30 Rock as Abby, a super girly, flirtatious female writer hired to work on the show.
She was also in season two of Fargo as Betsy Solverson.
"USS Callister" – Jimmi Simpson
Another of the USS Callister's crew, Walton.
Where you've seen him before
He is probably best known as Gavin, a hacker in seasons two and three of House Of Cards. It's Always Sunny in Philadelphia fans will recognise him as one of the McPoyle brothers and more recently, as the younger version of Ed Harris' Man In Black on Westworld.
Up until a few years ago, Jimmi was married to Melanie Lynskey, the actress who played Piper Perabo's conventional best friend Gloria in Coyote Ugly. Niche knowledge over here.
"USS Callister" – Billy Magnussen
Billy plays evil Baldak; a Thor/Jason and the Argonauts kind of baddie.
Where you've seen him before
Those of you who watched the O.J. Simpson retelling, An American Crime Story will remember Billy's unforgettable performance as Kato, the guy who lived in O.J.'s pool house. Elsewhere he played Elizabeth Olsen's awful brother Nicky in Ingrid Goes West.
Billy is set to appear in the much-anticipated live-action remake of Aladdin as Prince Anders.
"USS Callister" – Michaela Coel
Michaela Coel is another member of the Star Fleet crew, Shania.
Where you've seen her before

If you're not following Michaela on Instagram already then rectify immediately. She is an absolute delight.
"Crocodile" – Kiran Sonia Sawar
In this memory-messing film, Kiran plays a woman investigating an accident.
Where you've seen her before
Kiran is probably best known for her appearance as main character Salma in the incredible BBC Three drama Murdered By My Father, which tackled the devastating issue of "honour" killings.
Kiran owns an absolute blinder of a cat called Fynn.
"Crocodile" – Andrea Riseborough
Andrea stars as Mia in "Crocodile", a woman whose past comes back to haunt her.
Where you've seen her before
