The Sun in a Net is a 1963 film that became a key film in the development of Slovak and Czechoslovak cinema from the mandated Socialist-Realist filmmaking of the repressive 1950s towards the Czechoslovak/Czech New Wave and socially critical or experimental films of the 1960s marked by a gradual relaxation of communist control. The Sun in a Net received multiple votes in a wide survey of Czech and Slovak film academics and critics in the late 1990s asking them for their lists of the 10 best films in the history of filmmaking in the former Czechoslovakia.
