"Mannequin" is notionally a romantic comedy in which Andrew McCarthy plays a luckless department-store employee and Kim Cattrall ("Sex and the City") is an Egyptian princess reincarnated as a shop-window dummy, who comes to life when she encounters McCarthy, only to revert to mannequin status when anyone else is watching her. With her encouragement, he becomes emboldened in his career as a window decorator as well as falling in love with the princess. James Spader's oily, stammering executive is just one of the many examples of a film that tries way too hard to be funny, the sort of characterization that would be barely adequate for a TV commercial, let alone a 90-minute movie. Still, for fans of "Sex and the City" who might want to feast upon the spectacle of a younger Kim Cattrall, "Mannequin" might offer a measure of relief. "--David Stubbs"
