It is rare enough for directors to collaborate in theatre, even rarer in opera. Patrice Caurier (b. Paris, 1954) and Moshe Leiser (b. Antwerp, 1956) began their long collaboration in their 20s. They are now in their 50s, and since that first production of Britten’s A Midsummer Night’s Dream at Opéra de Lyon in 1982, they have never worked (or lived) apart. Cohabiting and collaborating, they are opera’s closest equivalent to Gilbert and George.

The BBC's reinvention of Doctor Who under the auspices of Russell T Davies has proved to be an inspired upgrade of a legendary 1960s marque fit to rank alongside BMW's resuscitation of the Mini, though it would hardly be sensible to argue that the new-look Doctor is distinguished by Germanic precision engineering or a coolly mathematical design philosophy. Quite the opposite.
