The opening sequence of Shaun of the Dead depicts ordinary people going through mundane daily routines to portray them as being like "zombies". Various shots show people working dead-end jobs with little thought or commuters checking their phones in unison. These shots establish the film's theme of modern life creating zombie-like conformity. The sequence then introduces the protagonist Shaun through an unexpected shriek that subverts horror conventions for comedic effect while also potentially foreshadowing Shaun as the film's antagonist.
