Terry Teachout taunts me with a clue to the source of his favorite film scene in the update to this posting. The scene in question is indeed a doozy. It is definitely noir. I thought at first Chandler, but then thought possibly James M. Cain, maybe the The Postman Always Rings Twice, but after a little sleuthing on my part (with a bit of help from Terry's cryptic clue) found out I wasn't far off.
And here is the scene in question...
There's a speed limit in this state, Mr. Neff, 45 miles an hour.
How fast was I going, Officer?
I'd say around 90.
Suppose you get down off your motorcycle and give me a ticket.
Suppose I let you off with a warning this time.
Suppose it doesn't take.
Suppose I have to whack you over the knuckles.
Suppose I bust out crying and put my head on your shoulder.
Suppose you try putting it on my husband's shoulder.
