Kiera Knightly's getting some Oscar buzz for "The Duchess" . . . it should probably be a lock for a Best Costume Design and Art Direction nominations. "Body of Lies" has two superstars at the top of the billing. It's based on the novel by David Ignatious of The Washington Post. Dennis Quaid does Disney again with "The Express." I can't say I know anything about "City of Ember" or "Quarantine." "Boy A" is also at Market Street Cinema.
