After filming completed on season 2, Krister Henriksson stated that he would not play Wallander again, having only signed the new contract because he thought the 2005 series could have been better. However, he later indicated that he would be interested in playing the role in an adaptation of the final Wallander novel, The Troubled Man (2015), because "it is the definite end".
The title "Vittnet" translates in English to "The Witness".
