Sisters (1972)/Dvd, Criterion Collection, DVD

Director/co-writer Brian de Palma's first foray into Hitchcockian screen suspense finds a reporter (Jennifer Salt) witnessing a brutal murder committed by the separated conjoined twin (Margot Kidder) of a Canadian fashion model (also Kidder), but cannot prove it to the authorities. As she digs into the killer's past, she uncovers a twisted tale of dementia, homicide, and the ultimate in "sibling rivalry." Dolph Sweet, Charles Durning also star; music by Bernard Herrmann. 92 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital mono; Subtitles: English (SDH); featurettes.
