The golden age of Swedish cinema was accompanied by significant social changes and questions about class society, gender relations, and the portrayal of these issues in film. Films depicted a greater degree of sexuality and women's freedom, which led to the development of pornography. This resulted in harsh reactions not only in Sweden but also in other countries. In the 1950s, the United States declared Sweden ”sinful”, which gave rise to the concept of ’the Swedish sin’. This thesis provides an overview of Swedish cinema with regard to the concept of ’the Swedish sin’ in the 1960s and the decades that preceded it. It explores the works of Bergman, Sjöman, and other directors that influenced Swedish cinema at that time. Additionally, it describes how critics, politicians, the church, and the public reacted to these changes in the film industry. Furthermore, it analyzes how the general production and distribution of pornographic material was perceived. Moreover, the thesis demonstrates how other countries, such as the United States, which as a leading film industry in the world, perceived these films and even banned some. All of this led to Sweden using the ’Swedish sin’ as a marketing tool in other countries and becoming proud of its progressive policies. Finally, the thesis also continuously explores the image of the woman on film.
