Most veteran filmmakers dwindle in their later years, churning out some of their weakest movies before their careers quietly end. Not Alfred Hitchcock, though, whose final flicks, while not all commercially successful, displayed an artist very much on top of his game—even if, as in the case of 1972's Frenzy, he was 73-years-old.
Heading back home to England after decades working in Hollywood, Hitch also went back to the kinds of stories he told throughout the 1940s, tackling screenwriter Anthony Schaffer's tale of a London serial killer who strangles ladies with a necktie and the wrongfully apprehended, innocent suspect who's trying to clear his name.
Emboldened by the changed standards of acceptance in 1970s cinema, Hitchcock delivered a more hardcore picture than ever before, filling Frenzy with the amounts of sex and nudity he'd previously kept hidden. Ever the tasteful visionary, however, he maintained the film's sense of dignity throughout.
