What the characters will do with this very British cycle of repression, release, and heroic self-denial is rendered in the script, by Ron Nyswaner ( Philadelphia , The Painted Veil ), in sometimes delicate but more often jarringly unsubtle ways.
It’s all quite sensitively and credibly handled by the deft cast, director (and acclaimed stage veteran) Michael Grandage and screenwriter Ron Nyswaner (“Philadelphia,” “The Painted Veil”).
