Everything You Ever Need To Know About Life...

 ... you can learn from:

Body Heat (1981)

Ned: Maybe you shouldn't dress like that.

Matty: This is a blouse and a skirt. 

I don't know what you're talking about.

Ned: You shouldn't wear that body.

God there is so much snappy dialogue in Body Heat, I love it so much -- I could've chosen a dozen other lines to highlight (see also here); it's why I think it's one of the most successful of the neo-noirs that popped up in the 70s and 80s (alongside Chinatown of course). The dialogue harkens beautifully back to the genre's heyday where the verbal playfulness between the lovers-to-be reveals not just their desire but their danger -- anybody who can whip out a double entendre this fast isn't to be trusted. And it also helps when the people are as sexy as William Hurt and Kathleen Turner are in this scorcher. Anyway we're here of course because Lawrence Kasdan's sweaty masterpiece is hitting 4K thanks to the Criterion Collection today -- go snatch up a copy stat! How hot is that cover art too? Humina humina!
