Watch MoviestoWatch. Documentary filmmaker Drahomíra Vihanová made a documentary Searching during the filming of František Vláčil's Concert at the End of Summer. The film was made between 1978 and 1979. Rather than a reportage, the film is an observation of the director's work. It alternates between black-and-white sequences with diegetic sound depicting the making of the film and colour sections that are silent or contain non-diegetic music, with František Vláčil at the centre of them, thinking and searching for inspiration and the ideal form for his film.
