The document provides a film analysis of the opening scene of "Black Swan" (2010). The scene shows the main character dancing with a partner in dark costumes under low lighting. The dance has sinister elements where the protagonist seems chased and restricted, foreshadowing how dance will drive her to lose her mind. Frequent camera angle cuts and dark costumes/lighting create a sense of confusion and make the dance threatening. The director uses techniques like low light, sinister music, and changing camera shots to turn an innocent act into something ominous and scary.
