Acclaimed shlock-horror director Frank Henenlotter (the Basket Case trilogy, Frankenhooker, Brain Damage) makes a deliciously perverse and hugely welcome return to outrageously repulsive form with his first film in 16 years, Bad Biology, a bizarre and twisted story of a genitally-endowed young woman's search for sexual fulfilment.

Opening with the voice-over line, "I was born with seven clits," the film introduces us to Jennifer (Charlee Danielson), an insatiable nymphomaniac whose multi-pronged sexual organ has given her a constant craving for penile stimulation. Unfortunately, the sexual satisfaction Jennifer seeks is proving very hard to find. Worse, each disappointing sexual encounter she experiences results in a two-hour pregnancy period that produces an always-unwanted mutant baby.

Unknown to Jennifer, just across town lies the solution to her frustration in the form of a young man called Batz (Anthony Sneed), whose own sexual shortcomings have led him to inject growth steroids directly into his penis. Thanks to some unfortunate side effects, Batz has now become the concerned owner of a 24-inch member with a drug addiction and a mind of its own! Naturally, Batz and Jennifer are destined to meet, but will their eventual encounter prove to be what either of them is looking for?

Proving he's lost none of his crazed enthusiasm for putting on screen what most people wouldn't even dare to imagine, Henenlotter delivers a jaw-dropping horror-comedy guaranteed to shock even the most hardened horror fans who think they've seen it all. From penis point-of-view shots to topless models in vagina masks and endless orgasms to an anthropomorphic cock bursting through walls and floorboards on a rampage of rape and destruction, BAD BIOLOGY is a tour-de-force of extreme cinema. Bizarre, outrageous, offensive and riotously funny, it is almost certainly destined for cult classic status amongst fans of off-the-wall horror flicks.

BAD BIOLOGY (cert. 18) will be released on DVD (£12.99) by Revolver on 16th February 2009.
