FILM, a thin skin, pellicle or lamina of any material, an opaque layer; a fine cobweb, gossamer or silk thread. Body sur face emanations in Epicureanism were films, supposedly percepti ble objects. In physics it is a liquid or gaseous coating; botani cally, a seed pod partition. Verbally the word means to cover or be covered with film. In photography (q.v.) a collodion or gelatin-coated paper or plate, or merely the coating is a film. Popularly, in the United States, it is the sheet or roll of material, such as celluloid, recording a moving picture (see MOTION PIC TURE) or still camera negative; the finished positive; or a com pleted cinema production. To "film a scene" is a very common term.
