In film

Collage film is traditionally defined as, “A film that juxtaposes fictional scenes with footage taken from disparate sources, such as newsreels.” Combining different types of footage can have various implications depending on the director's approach. Collage film can also refer to the physical collaging of materials onto filmstrips. Canadian filmmaker Arthur Lipsett was especially renowned for his collage films, many of which were made from the cutting room floors of the National Film Board studios.
