The history of trying to interact between the speaker and the listener in performing arts began from B.C. Through simple questions and answers, it induced viewers to participate, caused them to focus on the story, and induced a natural flow of conversation. But with the development of film invention and video technology, the interaction between producers and viewers has become less active, less passive or less interactive. If games and movies are combined with many elements of interaction, it can be a new attempt, and there is a high possibility that this interest and exposure will soon be linked to the formation of a new game genre. It can also increase the user's immersion and generate interest to meet their commitment to re-watch. To this end, this study explores ways to solve and improve the problems of existing interactive movies through case studies and effectiveness analysis of attempts to fuse games and movies, including existing interactive movies.
