Siticulosa (2025) explores the journey that historical artefacts undergo over time, from everyday objects and works of art, to archaeological treasures of high historical and sometimes economic value. Set in Puglia in southeastern Italy, Brennan uncovers a circuit where both farmers and passionate professionals are pitted against a criminal underworld. In an interdisciplinary investigation with branches into geology, archaeology, and ecology, the film moves around a landscape full of caves and caverns, while an original use of commentary text interjects itself into the objective discourse of the work.
