Ian McKellen is riveting: Hamlet, at Theatre Royal Windsor, reviewed

Ian McKellen in his early eighties plays the Dane in his mid-twenties. A production with such a strange innovation should be conventional in all other details so that the virtues and demerits of the experiment can be judged in the right context. But Sean Mathias’s show adds extra puzzles. Elsinore is a modern palace ruled by Claudius, in a charcoal suit, and Gertrude in a chic emerald dress, pinched at the waist. Nice togs. But the audience knows how a constitutional monarchy works and that a rightful heir succeeds automatically and peacefully. So why are these murderous nutcases roaming the corridors plotting to slit each other’s throats? That contradiction goes unexplained.

Connoisseurs will get it but newcomers will be baffled and bored. Modern dress productions should welcome everyone and not deter all but the cognoscenti.
