Because the series takes place in so many different locations in eight different countries around the world, by the end of the shooting, the cast and crew had completed 100,000 miles of flight time, the equivalent of going around the globe four times.
Instead of hiring directors to film individual episodes, the producers hired directors to film the individual locations. The Wachowskis directed all scenes set in Chicago, San Francisco, London, and Iceland; James McTeigue directed all scenes set in Mexico City and Mumbai; Dan Glass directed all scenes set in Seoul; and Tom Tykwer, who had co-directed Cloud Atlas (2012) with The Wachowskis, directed all scenes set in Berlin and Nairobi.
Capheus' accent isn't actually a Kenyan accent but more of a West African accent. This is because Aml Ameen shot in Chicago before he went to Nairobi and the dialogue coach in Chicago confused a Nigerian accent for a Kenyan one.
As of Thursday June 29th 2017 it was announced by Netflix that the series will get a two-hour finale special expected to air in 2018. In a heartfelt message by show creator Lana Wachowski, she announced that the online petitions and the noise created by shows untimely cancellation were successful. In her statement she mentions: "It is my great pleasure as well as Netflix's (believe me, they love the show as much as we do but the numbers have always been challenging) to announce that there will be another two-hour special released next year".
Because the series' directors are assigned a specific location rather than individual episodes, each installment has multiple directors. Individual directing credits are spread out randomly throughout the series, and given based on how many episodes' worth of running time each director was responsible for.
After Netflix announced in 2017 that there would not, in fact, be a Season 3, fans worldwide voiced their protest. Petitions and letters were passed around and many were outraged with the news. On June 8, 2017, Netflix posted the following statement: "To our Sense8 Family, we've seen the petitions. We've read the messages. We know you want to #RenewSense8 and we wish we could #BringBackSense8 for you. The reason we've taken so long to get back to you is because we've thought long and hard here at Netflix to try to make it work but unfortunately we can't. Thank you for watching and we hope you'll stay close with your cluster around the world. #SensatesForever." However, on June 29, 2017, it was announced that due to strong support from the fans, a two-hour series finale would air in 2018.
Nomi's inner arm tattoo,which is Ancient Greek for "Know Thyself", is also the translation for "Temet Nosce", a Latin phrase, which hangs above the kitchen entrance of the Oracle from the Wachowski's "The Matrix" trilogy.
The Sense8 cast includes notable alumni of Doctor Who. Sylvester McCoy, who plays "The Old Man of Hoy," was The Seventh Doctor from 1987 to 1989. Freema Agyeman, who plays Nomi's girlfriend Amanita Caplan, was The Tenth Doctor's companion Martha Jones from 2006 to 2010.
Critics have compared the basic idea of the show to Theodore Sturgeon's novel, "More Than Human," which coined the briefly-used 60's slang "blesh" (a portmanteau of "blend" and "mesh") to describe the psychic connection between the characters.
This marks the second collaboration of Tuppence Middleton and the Wachowskis, the first being Jupiter Ascending. Doona Bae was also in Jupiter Ascending as a bounty hunter hired by Tuppence Middleton's character.

In the fifth episode of Season Two, Nomi, Amanita, and Bug meet with a hacker referred to only as "The Guy". When "The Guy" finally appears, he wears a Guy Fawkes mask, insinuating that he is a member of the hacker group Anonymous. The same Guy Fawkes mask is worn by the eponymous hero "V" in "V for Vendetta", the film adaptation which was written by The Wachowskis and directed by James McTeigue (all of whom are directors of this show). Towards the end of the scene, "The Guy" gives a short monologue using many different words that start with the letter "V", much in the same way that "V" does at the beginning of the film. The exchange also takes place during episode five, which is represented in Roman Numerals by the letter "V".
Shortly after Netflix announced the two hour special set to conclude the show after it's cancellation, porn company X-Hamster offered in an open letter to fund an entire third season instead. It cited a history of representing diversity in sexuality as part of it's reasoning and stated that the show would not be changed to fit the company's brand. As of September 2017 however, there has been no public response by the creators or Netflix to this offer.
