The body is lyrical in dance, exaggerated and magnified in theater, yet it is restored to reality in film. The birth of film has further expanded and deepened the art of acting. Film acting presents the natural body through artistic processing, which draws on the rich expressions of body language from drama and dance. Actors create vivid characters through seemingly realistic yet artistically-crafted body expressions, engaging in the process of artistic production. The unique characteristics of film inherently determine that the body language in film acting possesses aesthetic traits distinct from those in other performing arts, such as dance and drama, and is adapted to its own needs.
