This paper has its purpose in groping the possibility of faction contents as the material for planning and development by analyzing the storytelling strategy based on the ‘double adaptation’ of faction contents. Faction, a newly-coined word that was made by putting fiction and fact together, is certainly a useful field when considering the concept of adaptation of the original movie. Already many debaters have agreed to the commercial value of faction contents and are presenting methodologies of planning and development of various shapes. The debater explain by comparing the concept of ‘multiple adaptation’ of OSMU and the concept of ‘double adaptation’ of faction contents and explain that this Adaptation is a process of a unique Adaptation that occurs in faction contents. ‘double adaptation’ can be understood as a process of adaptation and as converting twice on the basis of a certain strategic purpose, that is an identical storytelling. ‘double adaptation’ is a term that was named in the viewpoint of the movie that is the final result that went through the process of the first adaptation and was converted secondly. In addition ‘double adaptation’ and the difficulty of the establishment of plot that occurs in the process of genre adaptation and the adaptation of storytelling of this should be distinguished. The strengthening and expansion of storytelling that occurs in the process of adaptation is not something for the completeness of the adaptation but a core principle that makes the value of the adaptation. What is important is to understand the law of storytelling that exists beyond media and genre. The types of faction movies that were double-adapted can be divided into three types. The debater divides the types into the motive adaptation type, the storytelling adaptation type and the mixed (motive+storytelling) adaptation type and explains the contents of each adaptation. The motive adaptation type is a representative case of the tendency to use the original work only as the part of material and is a adaptation type that cannot easily obtain commercial possibility even though it goes through the process of ‘double adaptation’, and it is thought that the storytelling adaptation type is a adaptation type that more showed the possibility of a commercial success as a compared concept. Lastly the debater explains that the mixed adaptation type that digs out material and converts the storytelling of this is a type that can provide the motive of faction movies and adapt the storytelling that puts genre together at the same time. In conclusion, in the study about ‘double adaptation’, in the first adaptation faction contents are adapted into the first original work and in the process of the second adaptation the plan that can strengthen and expand the element of storytelling that occurred in the process of the first adaptation was let known. Finally faction contents are recognized in the present context thoroughly and therefore have the same way with works that participate in the reality which are one of the characteristics of Korean movies. For this reason this paper presents the storytelling strategy through the principle of ‘double adaptation’ in a point other than ‘multiple adaptation’. In addition it has the purpose in studying the existing cases of this and also in presenting a strategic methodology of ‘double adaptation’. Faction contents make various interpretations of individuals by themselves and let us feel commercial possibility and attraction of movie in that we indirectly experience real stories or elements of real stories through movies.
