This work relates to the inherent transformations to the transition from literary medium to cinematografic one.To study this issue, a double corpus was analysed, formed on one side of three textes taken from remembrance of the things past, on another side their respective film adaptations namely Swann in love of Volker Schlöndorff, The Time regained of Raoul Ruiz and The Captive of Chantal Akerman. Using this corpus, we were able determine the types of processing involved as well as the implemented strategies and the mecanisms underlying those latter. From this point of view, the practice of transposition is no longer matter of fidelity but a transtextuel dynamics that results in three inter semiotic links wich are resistance, deviation and extension. Thus filmic transposition becomes a language and the adaptation a kind of speech
