Before one can consider such niceties as eroticism, story, or performance, the camera has to be pointed in the general direction of the actors, and remain in focus (that’s where the little ring around the lens comes in handy). Charlie Diamond is a solid director, but Opportunity Knocks rings all the wrong bells.

The story is about an all-female house cleaning service that fronts callgirls, the cast listing is incomplete and the sex scenes really never ignite.
