Mary & George review: Bawdy bonkbuster fails to do justice to royal drama

Sex in period drama and actual royal romps have had an inverse relationship. In a former era, when Fergie was toe sucking on a yacht and Diana was sharing her husband with another woman, period drama about the royals – think of all those Kenneth Branagh adaptations – was buttoned up, stuffy and respectful. Thirty years later, the current generation of young Windsors are notably less scandalous, and yet on screen everything’s gone a bit Jilly Cooper for fictional royalty.
