Before '10' was released in America, its producers were so certain it was a clinker that they tore up contracts for two other Blake Edwards pictures. The miscalculation was understandable. Much of the film comes on like a Jill Clayburgh picture someone rewrote for Bob Hope, with Moore playing an ageing Unmarried Man who pursues lubricious women (rating them out of an ideal ten) to stave off menopause. Technically it's atrocious, trading on absurd coincidence, lame slapstick, and some peculiarly ugly photography. But the studio failed to see that Edwards had hit on a subject (male sexual insecurity) which was bound to strike a chord with the post-Clayburgh audience. The climactic love scene - in which Moore proves utterly unable to perform when he gets his emancipated dream woman (Derek) to bed - is very funny and represents a real catharsis in the history of Hollywood romance: Dudley Moore became the first actor to turn screen impotence into superstardom.
