In Song's other works, such elements sometimes feel forced or self-consciously arty, but here they blend with the otherworldly presence of the island and add a sense of mystery.
Git (which means either a triangular flag or "feather" in Korean) is surprising in several respects.
Comprising works by Jang Jin (Someone Special), Lee Young-jae (Harmonium in My Memory) and Song, 1.3.6 was intended to explore environmental themes and was slotted to open the first Green Film Festival in Seoul in late October.
Alas, the festival's expectations were confounded, first in that only Lee Young-jae's work really engaged environmental issues in a direct way (the other two were merely set in rural areas), and second by the fact that Song went out and shot a 70-minute film.
That all changed however, after Marathon had its press screening.
