Maybe Hitch has always wanted to be this explicit, and the times/censors just haven’t allowed it. This is his sweariest, nudiest, grimiest movie, starring nobody, about a woman-strangling sex maniac who frames his buddy for his crimes. Double featuring with Gun Crazy – this one is less naturalistic, or maybe people in Britain just talk like this.
Our guy Jon Finch (Polanski’s Macbeth the year before) is washed up and broke, tries to get cash from his ex (Barbara Leigh-Hunt, Lady Macbeth in a different production) right as she’s serial-killed, so Finch becomes the prime suspect. He’s caught but escapes, and the noble cops keep following leads even after his arrest, so justice is eventually served. Hitch’s particulars have changed, but the structure is standard. Some attempts at levity worked for me (Bob dumping a body in a potato truck, then getting taken for a potatoey ride while searching for an incriminating pin he dropped), and some did not (the lead detective’s wife serving trendy foreign cuisine to her crestfallen husband).

Our guy Finch is also friendly with next victim Anna Massey (Peeping Tom):
