Career
He directed 32 films between 1939 and 1970. As an already established professional, Čáp moved to Ljubljana in 1952, following an invitation by Branimir Tuma, director of Triglav Film. His first Yugoslav film, romantic comedy, had elements of Heimatfilm and pre-World World War II Czechoslovakian and Austrian melodrama, and proved highly successful both artistically and commercially, as did its sequel.
In 1956 Čáp shot one of his best-known films, Die Geierwally (The Vulture Wally), based on the novel by Wilhelmine von Hillern, in Germany.
X-25 javlja ("X-25 Reports", 1960), a World World War II spy thriller set in Zagreb, saw extensive international theatrical release. However, after his poorly received comedy Naš avto ("Our Carolina", 1962), Čáp was unable to find work in Yugoslavia, and he turned to directing films and television series in Germany and Austria.
