Marshmallows. That's what this movie is like--light, fluffy, not much substance, but enjoyable when you're in the mood. Nod to the classic screwball comedies of the '40s and '50s throws harried single mom/architect Pfeiffer and political columnist/weekend dad Clooney together when their kids, who attend the same school, miss a class field trip. Naturally, they take an instant dislike to each other, but are forced to cooperate to solve the daycare situation. An accidental switching of cell phones provides the chance for repeated encounters, and growing mutual interest. Predictable, but pleasantly so. No matter how hard she tries, Pfeiffer always looks good, and Clooney has that cocked head, devilish grin thing working overtime. Screenplay by Neil Simon's daughter Ellen supplies all the elements for a fine date movie.
