It takes a while for “Cheri’’ to limber up and get to the heart of the matter. A Belle Époque romantic drama reuniting some of the talents from 1988’s “Dangerous Liaisons’’ - director Stephen Frears, star Michelle Pfeiffer, writer Christopher Hampton - the movie at first seems a waxwork parody of Merchant Ivory-style filmmaking. It’s all bustles and brocades and arch dialogue, and there’s the additional incongruity of a California blonde amid the 1890s stemware.
Yet Pfeiffer has worn period gowns before, in “Liaisons’’ and 1993’s “The Age of Innocence,’’ and she has worn them well. If her voice remains flatly American, as an actress she’s alive to the genre’s diplomatic nuances - the way a woman in a corseted society can say one thing while meaning the exact opposite.
