Contemporary Ober-babe Jessica Biel steps into the snappy banter of Noel Coward’s roaring’20s in “Easy Virtue,“ and it’s an awkward fit. Simultaneously, director Stephan Elliott tries to make Coward’s world more accessible to today’s audiences with modern visual flourishes, and those feel uncomfortably forced, as well. The players who play it straight—Kristin Scott Thomas, Colin Firth and Ben Barnes—make moments of “Easy Virtue” sparkle as they should.
