Who'll be telling Renee Fleming what to do with her hands in her final Covent Garden performance?
The most intriguing rumour circulated in this month's Opera magazine is that Christoph Waltz is to direct a new Rosenkavalier at the Royal Opera House in 2016-17, where Renee will play the Marschallin in her Covent Garden farewell.
The Oscar-winning star of Inglourious Basterds doesn't appear to have directed anything before, apart from an obscure TV movie. But he studied singing and opera in his native Vienna before turning to acting, and he's a keen operagoer.
Years before his Oscar, Waltz proved himself as the finest of actors with a guest appearance in the finest of Austrian TV series, Kommissar Rex. His role as an evil doll-maker who dresses up women and moulds them to his will can only help with his Renee-wrangling. Watch him in the clip above, and check out the one below if you want to know how it ends (and catch a glimpse of Rex).
