Most people will probably see the film because it stars Judi Dench. Even though she plays the title role, most of the story is taken up with the younger version of her character (Sophie Cookson).  It’s based on the true story of a woman who shared England’s nuclear secrets with Russia via her lover and his sister. Even though there are 2 romantic entanglements, the constant flashback narrative unfolds with cold objectivity and not much passion. None of the performances are especially potent and the direction by Trevor Nunn, who’s mostly known for this innovative theatrical productions, lacks much real drama. History buffs might enjoy seeing this tale unfold, but others are likely to be disappointed by the competent, but rather flat recounting.
