The disquieting root of Chloe Domont's slinky, slick feature debut “Fair Play” lies in the face of Luke (Alden Ehrenreich) as he learns that his fiance Emily (Phoebe Dynevor) has been given the promotion at their Wall Street hedge fund he thought was his. Ehrenreich, a cunning actor here given a part to chew on, conveys the moment with the just right mix of of support for Emily and shattering woundedness. After, Luke kneels to propose.
