The Happy Hooker (1975)

Well, there's not much smut to be had here. Not much humor, really, either. So what does this film have to recommend it? Well, Lynn Redgrave wears a series of smashing early-70s outfits--floppy hats, go-go boots, backless evening gowns, big-sleeved minidresses... and the other hookers have some fresh attire as well (some charming negligees, lavender disco dresses, etc.). And some of the scenes of her tricks are mildly amusing (although many inadvertently so), particularly the one where she does a reverse striptease while reciting a business report.

Still, it starts off excruciatingly slow and you can see what plot twists there are coming a mile away with bludgeoning sticks in hand. And the party scenes in the brothel aren't nearly as much fun as you'd expect, considering as the 70s was a golden era for movie party scenes and this is supposedly a whorehouse. Not worth watching, really, although it is worth flipping back and forth to if there's not much else on.
