witness to murder

Hitchcock made the witnessing of murder central to his psychological thrillers, forcing viewers into complicit observation through subjective camera work and unreliable perspectives.

In 'Blow-Up', Antonioni explores the ambiguity and moral implications of witnessing violence through the lens of a photographer who may or may not have captured a murder.

De Palma consistently explores the theme of accidental witnesses to murder and the psychological burden of knowledge in films like 'Dressed to Kill' and 'Body Double'.
