She is persuaded to come quietly under the guise of filming her new movie’s climactic scene, so there are naturally a lot of studio lights on the scene. Wilder used the abundance of light to his advantage, with the lights in the background, contrasted against Norma’s head, contributing to the lingering sense of unease. There is also a very soft aspect to the picture, which could be taken to represent Norma’s own insane view that all this attention (from homicide investigators) can only be good for her own career prospects. The shot is also very slightly out of focus, which increases as Norma advances on the camera in the last few seconds, which further cements Norma’s loss of any grasp on reality.
