Following a disagreement with a sign in a department store, the character Jonathan, played by Andrew McCarthy, finds employment thanks to the store’s owner, Estelle Getty. This doesn't sit well with Richards, portrayed by James Spader, particularly as Jonathan begins attracting customers with his window displays. For this talent, he owes a debt to an Egyptian woman who appeared after a disagreement with her mother in a temple at Edfu. Kim Cattrall plays this spirited and cheerful character, but she only exists when they are alone; otherwise, she’s simply a mannequin. Unbeknownst to them, Richards is scheming with another store owner to drive the business under and acquire it cheaply. The question becomes whether Jonathan's window displays can generate enough revenue to keep the shop afloat before his plans are revealed or he ends up committed for his unusual attachment to a life-sized plastic doll. McCarthy, who I always considered one of the best of the “Brat Pack,” injects an infectious energy into what is otherwise a rather bland and predictable, almost slapstick comedy where he and Cattrall have good chemistry. Spader, however, doesn't fare so well, and aside from a few spirited moments from Getty, most of the cast struggles to elevate the material in this cheesy romantic comedy. The film’s only real distinction comes from the “Starship” song "Nothing’s Gonna Stop Us Now" that plays at the end, and a scene featuring furs in the shop window—that's about as far as it goes. The originality and appeal of this type of movie had clearly diminished by this point, and this feels like a particularly minor example, but for those who remember it from when it was new, it can still elicit a pleasant feeling of nostalgia.
