Margaret Honda's site-specific Films work with sunlight, existing architecture, and the viewer’s presence to reconfigure standard elements of film projection. Honda is interested in the materials and mechanics of analog motion picture production rather than its capacity for telling stories, and she uses existing structures and environmental conditions as the basis for her interventions.

For Film she works with cinema lighting gels, which come in manufactured sets in a range of colors and tones and typically serve to adjust the color temperature of a given scene. Identical in size, the gels function as film frames, and each window frame forms a reel of film. Instead of a projector, the sun provides light while visitors lend motion to the work, frame by frame, as they pass through the space. Moviegoers typically sit still, in the dark, and watch a single film from beginning to end. Here, the viewers are instead in motion, the space itself is full of light, and the films can be viewed more or less at once—forwards or backwards. The full duration of the installation functions as an extended single screening, open-ended and unrepeatable.
