In 2025, Andrej Košak's documentary "Punk under the Communist Regime" was released, exploring the history of the Ljubljana punk scene between 1977 and 1985. The film examines the emergence of Slovenian punk and the political reactions to it within the social atmosphere of the final years of Yugoslav socialism.

The documentary features bands such as Pankrti, Berlinski Zid, Ljubljanski Psi, Grupa 92, Buldožer, Via Ofenziva, Kuzle, Šund, and Otroci Socializma. A characteristic of the era was that many bands were formed by high school students who quickly entered an active concert life, while the authorities watched the movement with growing suspicion.

According to Košak's film, Ljubljana became a distinct countercultural center in the early eighties. Through punk, young people reacted to the unifying politics of the Yugoslav system and created new communal spaces for themselves. The film also emphasizes how party structures and state organs tried to keep the rapidly growing scene under control.

The screenplay was co-written by Andrej Košak and Dušan Moravec. The cinematographer was Gregor Kitek, and the editor was Maja Kokić. The production is a Slovenian, Bulgarian, and Serbian co-production.

Andrej Košak is a well-known director in Slovenian cinema. His previous works include Outsider, Headnoise, State of Shock, and All Against All. He regularly deals with social and political themes in his films, and "Punk under the Communist Regime" continues this line in documentary form.

Recently, the film has been featured in the programs of several international documentary film festivals, including DokuFest, Beldocs, and the Sofia International Film Festival.
