I thought the following exchange between the two male characters a little startling because of what we're experiecning today with global warming/climate changes. Meeting each other for the first time, they're both uncomfortable since they're both interested in the same woman and make a clumsy attempt at conversation. In Janet Leigh's apartment, standing in front of the fireplace, they have the following exchange, which isn't verbatim, but close:
Carl Davis/Corey: "They say it's going to be a white Christmas this year."
Steve Mason/Mitchum: "That’ll be nice."
Carl/Corey: "Usually now a days, all we get is slush."
Steve/Mitchum: "Yeah, ten years ago, we had snow all the time."
Carl/Corey: "Now, it's all slush"
Stever /Mithcum: "Yeah. Must be because of the atomic bomb."
That wasn't the exact wording, and I don't remember who said what, but that's the gist of it. It was a bit startling to hear two characters make note of climate changes and the possibility those changes had to do with humanities interference with nature sixty years ago!
