While the most common form of film adaptation is the use of a novel as the basis, other works adapted into films include non-fiction (including journalism), autobiographical works, comic books, scriptures, plays, historical sources and even other films. Adaptation from such diverse resources has been a ubiquitous practice of filmmaking since the earliest days of cinema in nineteenth-century Europe. In contrast to when making a remake, movie directors usually take more creative liberties when creating a film adaptation, changing the context of factors such as audience or genre.
