"Did you know Neville that my late husband, Mr. Davidson, was up a 5:30 every morning of his life?
And by the time he brought me my cup of tea, which he did punctually at 9:15, he would have
cleaned the whole house and been so quiet about it that in 14yrs he never woke me once. Not once."
...
He sure stepped in it.
But it IS a Hitchcock picture. So, maybe he planned to over-insure her and...
Though the National Organization of Women(NOW) protested against Frenzy for its "treatment of women" (but it IS about an evil man who rapes and kills women -- hardly on his side)....the movie start to finish actually shows us a series of relationships in which the woman is more successful or smarter or...dominating than the man.
This little bitty moment early on in Frenzy -- with the domineering woman about to run the life of her milquetoast husband -- is but one small taste of it.
As for the rest:
Brenda Blaney has divorced Richard -- much as she loved him, she couldn't take his temper and his failures. Now, SHE runs a successful business and HE has been fired from his job at a pub, facing homelessness.
Mrs. Oxford keeps telling her husband Inspector Oxford(over those horrible dinners she serves him) that Richard Blaney CANNOT be the killer -- what man would rape his ex-wife ("Look at us, we've only been married 8 years and I can hardly get you to look at me.") Inspector Oxford keeps putting Mrs. Oxford down on her "woman's intuition" , but she's RIGHT -- Blaney isn't the killer, its Rusk. Late in the film when Oxford says "It looks like we put the wrong man away," Mrs. Oxford corrects him: "What do you mean WE? YOU put him away."
When Blaney seeks the aid of his old RAF buddy Porter -- the husband wants to help Blaney but his shrewish(or perhaps smart) wife does NOT want to help. And look at them -- he's a rather soft, goofy looking guy, SHE is pretty hot looking -- though severe and older now. The way I figure it, Hetty Porter was probably a barmaid in one of Porter's pubs , and he had money and she had looks and she got him to marry her and...resents him. But she wears the pants -- Mr. Porter has to withdraw his offer to help.
Add those couples to the couple at Brenda's agency, and you have a tale of how 1972 women are already starting to outpace their men. NOW picketed the wrong movie.
And as for the rapist-killer psycho Rusk? He's impotent with women unless in the act of killing them. They evidently intimidate and enrage him ("Women! You're all the same...I'll show you.") He's the "male rage" of the movie, striking out at these successful women(and let's not leave out Babs, who truly loves Richard and protects him -- before Rusk kills her too.)
