A compilation film, or compilation movie is a film composed of scenes and shots taken from two or more prior films and edited together so as to make a new film, whether on the same or a different subject. The most common example would be a documentary film on an historical event composed of footage from various newsreels and other film documentaries on the same subject. New footage and/or a new soundtrack may also be included in a compilation film, but the compiled, older footage makes up the majority of its principal material. Compilation film does not include, however, a simple editing together of several short films, complete in themselves and distinguished as such from each others, which should be considered as film anthologies.
