Complex motion animation has been produced by the hand of an animator, it takes time and effort. This paper presents a content creation support system for missile animation with complex motion. These problems can be solved by generating a representation of a complex operation automatically that requires technology. The purpose of this system is to support the animator to be able to create a complicated missile animation easily. Therefore, firstly the complicated missile animation and camera work of "Itano Circus" were observed. Next, the system which missile path and camera work could produce automatically in Unity was made. Finally, two experiments and a questionnaire evaluation were performed. The first experiment evaluated whether the animation can be produced easily. The second one evaluated whether the animation which is produced can express complex missile animations.
