<P> Unlike the first season, where the Wachowskis and Straczynski split the number of scripts in half and worked remotely from each other, writing for the second season was performed by Lana and Straczynski by collaborating inside a shared writers' room . David Mitchell and Aleksandar Hemon worked as additional writers on the second season and were credited as "consultants". They spent a week in September 2015 with Lana, Straczynski, and script supervisor Julie Brown, proposing to them situations to be further developed by Lana and Straczynski . Later, once filming began, Lana did a lot of rewrites on a daily basis as she got inspired by the locations, actors, and so on, even on the set . When the series finale special was announced, Lana, Mitchell, and Hemon returned as writers . </P> <P> On June 20, 2014, Deadline Hollywood announced the cast of the eight lead characters, along with Freema Agyeman, Naveen Andrews, Daryl Hannah, Alfonso Herrera, Eréndira Ibarra, and Terence Mann . For the roles of those characters living outside of America, the filmmakers wanted to assemble a cast of international actors that matched the nationality of their respective characters, if possible . For example, Doona Bae, Tina Desai, and Max Riemelt are from Seoul, Mumbai, and Berlin like their respective characters . Jamie Clayton is a trans woman like the character she plays . In November, Deadline Hollywood wrote than Christian Oliver had joined the cast as a recurring villain . </P> <P> On April 26, 2016, Deadline Hollywood reported that Aml Ameen abruptly left production a couple of episodes into filming of the second season over a conflict with Lana Wachowski that started during the table read for the season and progressively got worse . Subsequent to Ameen's departure, the role of Capheus was recast to Toby Onwumere after a seven - day auditioning process . Earlier in April, Kick Gurry revealed he had been cast in the second season . In May, Deadline Hollywood reported Ben Cole had been cast as Todd, a sensate who would rather be "normal". In September, Sylvester McCoy reportedly revealed he filmed three or four episodes of the second season . </P> <P> To properly tell the international aspects of the story, filming for Sense8 took place almost entirely on location around the globe . In the first season they filmed in nine cities located in eight countries: Berlin, Chicago, London, Mexico City, Mumbai, Nairobi, Reykjavík, San Francisco, and Seoul . Production began on June 18, 2014, in San Francisco . The writers wanted to feature an event in each city . They were able to schedule the Pride scenes with its Dykes on Bikes on the Dyke March in San Francisco, the Fourth of July fireworks celebration in Chicago, and the Ganesha Chaturthi Hindu festival in Mumbai . Filming wrapped in Iceland on January 21, 2015 . By the end of the shooting, the filmmakers had completed 100,000 miles of flight time, or four times around the globe . </P>
