Quote:
"[Caroline] Leaf made Two Sisters by etching each individual frame, without the use of a camera. Like her other award-winning films—made by pushing around sand or oil paint on underlit glass—nothing remains at the end except the film strip. No cells, models or drawings; none of the usual paraphernalia of the animation artist. The style is minimalist, yet with a few etched lines suggesting fingers at a typewriter, Leaf is able to conjure a writer's project in the space of seconds. Within eleven minutes, Two Sisters conveys more emotional depth than many full-length feature films."
