Touch of Her Flesh (1967)

Richard's wife is a real winner.  While he's at work she cheats on him in a long, tame 1960s sex montage.  When Richard comes home unexpectedly and walks in on her, his horror and our boredom force him wordlessly out the door and into the street where he is hit by a car.

Richard ends up with an eyepatch and a wheelchair, ranting endlessly about his hatred of women and his need to kill hookers, who he insists die naked in public.  Oh sweet Richard... sweet, crazy, murderous Richard.

His killing spree starts when he puts slow acting poison on some roses and sends them to a topless dancer.  After being priced by a poisoned thorn, she goes back on stage and slowly collapses.  Yup, it's a long way to go for the first death.

The film features nudity, tons of hairspray, a lack of dialogue, death by blowgun, and a woman who puts straightening her hair above making sure she is safely away from the killer.
