I wasn't at all surprised to find that erotic Cat III thriller Evil Instinct was the most watched hotel pay-per-view film in Asia: with copious female nudity and soft-core sex aplenty, it's perfect entertainment for lonely, bored businessmen with idle hands.
The plot, for what it's worth, sees police inspector Sam Hui (Bowie Lam) mixing business with pleasure when he becomes involved with tasty insurance company executive Penny Ng (Naked Killer's Carrie Ng), one of several suspects in his investigation of a series of grisly sex murders. Meanwhile, Penny's curvaceous work rival Wendy (played by the lovely Diana Pang Dan) unwisely sets out to steal her colleague's customers by offering them kinky sex.
If any of this sounds vaguely familiar, it's because Evil Instinct is Hong Kong's answer to Basic Instinct; writer/director Barry Chu even goes so far as to include his own take on Sharon Stone's infamous interrogation scene (although Carrie Ng falls short of flashing her beaver to the cops). Unsurprisingly, the film fails to match its Hollywood counterpart in terms of intrigue and suspense (Chu is no Joe Eszterhas or Paul Verhoeven), and despite veering into seriously weird territory for a while by having Penny become addicted to an experimental snake serum, it is actually fairly dull stuff whilst the women are fully dressed and not getting fruity.
It's a good job then that the girls regularly shed their clothes and indulge in hanky-panky, with Ng wearing a selection of figure hugging outfits and getting it on with lucky Sam on several occasions, another smaller-breasted-but-still-rather-yummy Asian strumpet doing naughty things with ice cubes, and the delectable Pang Dan having sex in the shower and sporting a kinky PVC S&M get-up to please a discerning client (Wowzer!!).
