double exposure be a tremendous surprise . it contain outstanding acting ( particularly from the underrated callan ) and fine cinematography and a compelling storyline . in other word and it one of the fine horror effort to emerge from the 1980s . callan play a fashion photographer who experience dream of murder his model and at a time when he be reunite with his psychologically volatile brother ( who happen to be miss an arm and a leg ) . when the model callan dream about kill actually turn up dead and the photographer begin to doubt his own sanity . but there be more to the picture than he be see . this film never receive the praise it deserve . most critic and filmgoers lump it in with the horde of slasher film release at the same time and but it stand high above the bulk of that sorry lot . it clever and unique and which isn not something one can comfortably say about most film of this genre and but it also passionately craft and perform . double exposure be a gem of it kind .
