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. Filmmaker and historian Jay Leyda first coined the term "Compilation Film" in his book Films Beget Films in 1964, but it appears that there have not been active discussions around the topic since. This could be due to the lack of accessible and available shots that are required to complete a coherent project. Scholar Keith Beattie stated that without relevant clips, it is challenging for creators to utilise such format to put forward comprehensive arguments. Propaganda Some of the earliest compilation movies were propaganda films. A famous example is the German Nazi propaganda film Der ewige Jude (1940), where only a small part consisted of new footage, namely the scenes with Jews in a Polish ghetto and the animated maps. The lion's share of the film was filled with old newsreel footage showing Albert Einstein, Anna Stern, Rosa Luxemburg and Adolf Hitler and clips from movies with and by Charlie Chaplin, Ernst Lubitsch and Fritz Lang. Other countries, including the United States and Great Britain, also made propaganda films with archive footage to present themselves in the style of a documentary. Compilation films based on popular film and television series In the years before the invention of video stores film companies released compilation films in which the best episodes of a film serial were put into one movie. One of the earliest examples were Walt Disney's "package films", based on his popular short animated films. After television became popular during the 1950s some television series episodes were compiled and edited into one film. A famous example was the 1955 TV series Davy Crockett, which was released as the cinematic feature Davy Crockett and the River Pirates
