"The only beat I hear is the beat of my own heart..."
The image above is a photograph, but the voice-over eminates from actress Barbara Stanwyck. In this speech delivered in nicotine, Stanwyck conveys the theme of Eastside, Westside (1949). Unheard by other characters, Stanwyck's words are audible to us.
Character and viewer comingle in voice-over. The character lights a cigarette. The viewer inhales it.
