movie adaptation

A film adaptation is the transfer of a work or story, in whole or in part, to a feature film. Although often considered a type of derivative work, film adaptation has been conceptualized recently by academic scholars such as Robert Stam as a dialogic process.
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 other films. From the earliest days of cinema, in nineteenth-century Europe, adaptation from such diverse resources has been a ubiquitous practice of filmmaking.
