A film adaptation is the transfer of a written work, in whole or in part, to a feature film. It is a type of derivative work. A common form of film adaptation is the use of a novel as the basis of a feature film. Other works adapted into films include non-fiction (including journalism), autobiography, comic books, scriptures, plays, historical sources, and even other films. From the earliest days of cinema, in nineteenth-century Europe, adaptation from such diverse resources has been a ubiquitous practice of filmmaking.
