John Lynch, Anamaria Marinca and Jenessa Grant are joining "Tin Star".
The "Fall" star and "The Missing" actress have joined the second series of the Sky show, with Tim Roth, Christina Hendricks, Genevieve O'Reilly and Abigail Lawrie reprising their roles in the hit show.
Tin Star creator Rowan Joffe and executive producer Alison Jackson said: "We are thrilled to be given a further opportunity to delve deeper into the characters we had such fun with in series one.
"A second series of Tin Star lets us build on the established world of Little Big Bear, but also gives the audience a glimpse of another intriguing community and provides us with a family who are strangely unsettling for our hero Jim Worth. We are delighted that John, Anamaria and Jenessa have joined our wonderful cast."
At the end of the first series, Police Chief Jim Worth (Tim Roth), his wife Angela (Genevieve O'Reilly) and their daughter Anna (Abigail Lawrie) were left dealing with the chaos that followed Jim and his alcoholic alter ego Jack Devlin from the UK. The second series picks up where they left of, with Worth in the remote Rockies wilderness with his family as they come to terms with what's happened. Anna, looking for an escape, is taken in by the Nickel family, headed up by Pastor Johan (John Lynch) his wife Sarah (Anamaria Marinca) and daughter Rosa (Jenessa Grant), and hidden with the religious community, the Ammonites.
Series one of "Tin Star" is currently available to watch on demand on Sky and NOW TV. Series two - which is being filmed in Calgary, Canada now - is scheduled to air in 2019.
