With the development of visual media, the skills and capabilities of actors have continuously evolved. Consequently, the influence of actors has significantly increased across all aspects of film production, accompanied by a heightened societal interest in actors. The emergence of Hollywood's star system serves as a prominent example. While the expansion of actors' domains was a positive outcome of the star system's development, it also brought about various societal issues and negative impacts. The growing public interest led to heightened expectations and, at times, excessive scrutiny, affecting the psychological well-being of actors. Recently, the world lost another renowned actor, underscoring the impact of the extension of actors' societal influence. Based on this influence, the researcher aims to propose a new direction for future approaches to media acting. The objective of this study is to move beyond the traditionally emotion-centric method acting and restore and expand actors' inherent self-awareness. Drawing on the concept of 'self-reflectivity' that has developed in literature and film, the study will analyze media acting. Starting with the definition of self-reflectivity, the research will explore how it has evolved in theater and visual media. To enhance understanding of self-reflective acting, a comparison with the method of acting rooted in empathy will be presented, addressing issues with traditional acting approaches. The study proposes an actor-centric approach, focusing on the actor's self-awareness, and provides a basis for the concept of retroactive creation through concrete examples from previous cases. This research challenges and reinterprets issues with conventional tool-based and emotion-centric method acting. It also suggests an approach to ensure the psychological and physical well-being of actors, emphasizing the necessity of self-reflectivity in the central role of actors in the changing landscape of visual media. This presents a novel proposal for media acting approaches, paving the way for continued research that emphasizes embodiment. The researcher judged that "method acting," which has been developed with the star system, has so much expectation for the actor's "emotion," that it is difficult to protect the actor's natural emotional health from the many side effects mentioned earlier. As a complementary measure to this, we would like to propose a methodology that can allow actors to maintain a stable psychological-body state by incorporating "self-reflexivity" into media acting.
