A deleted scene refers to footage that has been removed, censored, replaced, or simply left out from the final version of a film or television show. (It is occasionally referred to as a "cut scene", however the different usage of this phrase in reference to video games makes this term uncommon in this context.) A related term is "extended scene", which refers to the longer version of a scene which was shortened for the final version of the film. Often extended scenes will be included in collections of deleted scenes, or also referred to as deleted scenes themselves, as is the case with for instance, Harry Potter and the Chamber of Secrets and Serenity.
