While it's a cinch that Portrait of Desire will never hang in the Louvre, there is enough enthusiasm and (dare I say it?) romantic arousal on the part of its mostly unknown cast to make the film a minor work or art worth your time.
Art gallery owner Buck Adams and secretary Stevie Taylor are given lessons in lovemaking by the sex-starved spirit of a young woman that resides in her picture (Karen Summer). This funky phantasm also calls upon some other "friends," a randy sailor and leather-clad punkette, for some other-wordly fun and games that are rich in erotic appeal and atmosphere. The lovely Summer works well with each of these characters, bringing out each person's "technique" for some memorable sex scenes.
If there is a drawback to the film, it would be a "subplot" featuring an untalented artist who insists on painting his models... literally... before showing her some special "brushstrokes" you don't find on a canvas. The two vignettes in themselves aren't bad, but seem unrelated to the film at hand and detract from the main characters.
Upon viewing the piece as a whole, however, these are minor faults that do not ruin a cohesive whole. For the patron who doesn't know "art," but knows what he likes, be sure to give this portrait a viewing.
