The lovely, quite busty Karen Boyer burst onto the British sexploitation scene way back in 1972 with a role in the hippy-dippy Skin-filled flick Four Dimensions of Greta. In spite of the title, the film actually had parts presented in three-dimensions, as the technology for displaying the fourth dimension (or “time”) wasn’t quite developed in the early-1970s, nor at the present. In any case, the use of 3-D glasses is a must, as there are quite a few scenes of humongous hooters being heaved directly at the viewer in all their eye-popping glory and without the glasses, they just look blurred. Karen managed to pull a few full-frontal scenes out of her hat for the flick, as did the likes of fellow 1960s sex kittens Minah Byrd, Leena Skoog and Felicity Devonshire, all of whom flashed the finest natural ass-sets to be sexpected from an early-1970s exploitation picture. (Oops… We’re detecting a few Freudian Slips back there…) In other words, don’t miss it, especially considering that Karen never went on to much else of note and she’s definitely worth checking out.
