It’s remarkable how over the course of just three “nightlife” features—Metropolitan, Barcelona, and this comedy set in the early 1980s—writer-director Whit Stillman has created a form of mannerist dialogue as recognizable as David Mamet’s, a kind of self-conscious, upper-crust Manhattan gab reeking of hairsplitting cultural distinctions. Fortunately, this time around the Ivy League characters project less of a glib sense of entitlement, making them more fun to watch, and Stillman himself gives more evidence of watching rather than simply listening. The characters include two young women in publishing (Chloe Sevigny and Kate Beckinsale) who find a flat together, their roommate (Tara Subkoff), an employee at the club where they hang out (the always interesting Chris Eigeman), a fledgling ad executive (Mackenzie Astin), a junior assistant district attorney (Matt Keeslar), and a lawyer (Robert Sean Leonard). Stillman does interesting things with all of them. 113 min.
