Frenzy (1972)

A serial killer is on the loose in London, leaving a bloody trail of death in the Alfred Hitchcock thriller Frenzy (1972). Hitchcock's second to last film he ever directed, the film revolves around the wrongfully accused Richard Blaney (Jon Finch), a former RAF officer turned barman who becomes suspect number one when his ex-wife (Barbara Leigh-Hunt) and his current girlfriend (Anna Massey), are found dead. The real killer is Blaney's buddy, the fruit merchant Robert Rusk (Barry Foster), who has been planting evidence to frame his old pal, and killing people wherever Richard finds himself. So, when Richard goes to his friend for help, he is arrested for the murders and realizes his friend is really the "Necktie Killer." While he's locked up, Chief Inspector Oxford (Alec McCowen) eventually comes to the conclusion that he has the wrong man. But since the circumstantial evidence implicating the bitter bartender is overwhelming, Richard realizes only he can save himself. He escapes from jail and heads for the hills. When word of the jailbreak reaches Oxford, the diligent detective goes straight to Rusk’s flat, thinking the wrongly convicted convict will exact revenge on his female strangling stalker, leading to a bizarre and explosive ending. Surprisingly enough, Hitchcock gave us some flesh in Frenzy. The first film from Alfred to feature real nudity, if you don't count the obscured shots of Janet Leigh in Psycho (1960), body doubles for Barbara and Anna give us two out of three Bs that will put your fleshy friend in a frenzy! Barbara Leigh's body double lets us see a bit of bush, and a closeup of her massive mams as a dude plays with them on the floor. And, Anna Massey's double flashes all three B's in the shower. Whoever those doubles were, they showed the kinds of bodies you want on your friends with benefits in Frenzy!
