Reworking motifs from both Rear Window and Vertigo, Brian DePalma updates Hitchcock’s examination of voyeurism and the dark intertwinings of love, eroticism and violence. De Palma brings these obsessions into the present day with this tale of death, deceit and the beginnings of a love affair between a struggling actor and a struggling porn star. The tacky milieu of B-movie production in early 1980s Los Angeles comes to seem like the decadent but harmless reflection of a bloody world of jealousy, abuse and murder, just as Body Double slyly suggests that voyeurism is the innocent counterpart to more violent urges.
