These two episodes were filmed on location in Skåne, Sweden, and Copenhagen, Denmark. Returning cast include Jeany Spark as Linda Wallander, Richard McCabe as Nyberg, Barnaby Kay as Lennart Mattson, and Ingeborga Dapkunaite as Baiba Liepa. Shooting took place in Ystad Studios, simultaneously with the third season of Swedish-Danish crime drama "The Bridge". The budget for the final season is 100 million Swedish kronor. The tax funded entities Ystad-Österlens filmfond and Film i Skåne have put three million Swedish kronor into the production according to Sveriges Radio. The new series was shot on several locations surrounding Ystad, including Mossbystrand, Östra Hoby, Vårhallen Beach, Tunbyholm Castle plus Blekinge Province and the Danish island of Zealand. On 30 October, several scenes were shot at the Norreportskolan, a local Ystad middle school. Several of the students participated as extras. The final three episodes had their world première dubbed into German on German network ARD, which co-produced them. They aired over three nights, on 25 December, 26 and 27, 2015.
