With the recent activation of the cultural contents industry, contents, which can create various added-values with a topic or a material, are being actively developed. Therefore, OSMU (One Source Multi Use)-one original work or one material is changed into various genres to make contents-is being applied. Starting from a literary work having solid epic, it has been spread to movies, dramas, or regional festivals a lot, and comic books that have epic like literary works are also used as the original source of OSMU. ``Grand Chef``, a comic book by Heo Young-Mahn, has a large circle of readers and uses various story materials, so it has led the expansion of OSMU that was restricted to literary works only. The cartoon, ``Grand Chef``, which is the original work of the film and the drama, is being published in a series now, and in 25 separate volumes published so far, about 100 stories are included, so it is quite difficult to use all of them as video contents that have some restrictions in time and production environment. Therefore, the film and the drama selected some proper episodes suitable for their characteristics, and then, created another story having consistency. In this process, there were some changes in the characters and the story was changed to be focused on ``a battle``, not an episode, through which dramatic tension became induced. In addition, the infortainment-like properties of the original work were used on Internet homepage. This paper intends to analyze the case that the comic book, ``Grand Chef``, was made into the story of the film and the drama respectively, and further, it intends to research the way of comic book-used OSMU.
