In order to understand this holewhole and huge mechanism , more precisely the „Theory of Adaptation” book-movie-games or vice versaof books/movies/games, we must understand the basisbasics of adaptation and those mechanisms that arecontribute to the making an adaptationof a very succesfuly forsuccessful adaptation that allows the audience to "see" a book, or "play" it like in thea video gamesgame. My work subject in orderaims to support and show the vastness of this huge and complex mechanism called „Adaptation” is the bookand focuses on Robinson Crusoe. I have chosenby Daniel Defoe. I chose this book as a consequence of the fact that beeing soit is a succesful book,the peoplevery successful one, as the attempts to adapt it intofor movies have were sobeen numerous. When we are speaking about adaptation, I think that the most appropriate definition should be the onethat of a product or of „a process of creation and reception suggesting the need of a theoretical perspective” ,(Linda Hutcheon, Theory of Adaptation, Routlage, 2006).
