WAG: Bob and Carol and Ted and Alice? 
I’m afraid not.
Would a slight hint help, as in maybe adding context to the banter between parties “A” and “B”?
Context is always helpful. 
Allows for its full expression of humor as well.
Let’s see:
Party “A” is one of two male roommates, who have invited party “B”, two female roommates in for drinks and dinner. The girls in party “B” were relaying of just how miserable the heat and humidity is and how it prevents them from getting a night’s rest. ( this elicits mirthful giggling from the girls in party “B” )
Sorry, doesn’t ring a bell. 
Correct answer:
‘The Odd Couple’ ( The original 1968 film )
“What is it with you and this death fixation?”
Aha! 
Never seen the movie, just the TV show. I’ll put it on my bucket list.
“You don’t trust me, do you? I don’t blame you. If there is to be a brave new world, our generation is going to have the hardest time living in it.”
I didn’t read the whole thread, but I doubt if anyone has mentioned this.
“Terrible nuisances teeth. You should have them all out.”
Here’s a hint: Spoken by a distinguished older women (played by a distinguished actress of yesteryear) to a young footman who is serving her at table.
Quite apropos for me given my recent dental woes…
Gloria Swanson in Sunset Boulevard?
A: “I was reading a book the other day.”
B: “Reading a book?!?” 
No, sorry…
Dinner at Eight, A: Jean Harlow, B: Marie Dressler. A classic exchange!
Yes! 
The rest of the exchange is too juicy to leave out:
JEAN: “Yes. It’s all about civilization or something. A nutty kind of a book. Do you know the guy says that machinery is going to take the place of every profession?”
MARIE: “Oh, my dear, that’s something you need never worry about.”
I definitely recommend it: better than the sitcom show. Darker comedy.
I was never fond of the show after the first season. The whole tone of it was different, more like Happy Days (which I could never stand either).
Well put! 
Here’s another b-i-i-i-g hint: the title is the name of a character who does not appear in the movie.
Baby Jane?
