In the wintry air of A Most Violent Year, a would-be business magnate named Abel Morales (Oscar Isaac) sports a handsome camel-hair topcoat. He’d like to achieve success the honest way, and that immaculate coat is like his shining armor. Problem is, this is 1981-era New York, the business is heating oil, and nothing stays clean for very long here. Writer/director J.C. Chandor is skillful with these details—this is a very intricate story—and quiet in his approach. Abel’s jacket is the flashiest thing about the movie.
