The article discusses the process of shaping the media image of Colonel Ryszard Kuklinski (1930 – 2004). The author argues that the feature film Jack Strong (directed by W. Pasikowski, Poland 2014) had importance in the public debate concerning this tragic figure in post-war Polish history. The article presents a series of journalistic materials from the press, in which the memory of R. Kuklinski is presented in dichotomous extremes between heroism and betrayal. A mixed media image of a soldier of Polish People’s Army cooperating with a hostile intelligence, fosters the myth of the new incarnation of Konrad Wallenrod.
