Collaborations for dance, theatre and other things are coming thick and fast at Sadler’s Wells nowadays - these are not halcyon days for pure choreography.

Christmas ballet would be unthinkable without The Nutcracker. But what kind of Christmas should it be? This year the UK fields an astonishing array of visions, from Biedermeier formality at the Royal Ballet, to Fanny and Alexander romanticism at Birmingham Royal Ballet, Elvis cartoons at English National Ballet, and expressionist German psychodrama at Scottish Ballet.

Is the look to be Beckmann, Bergman or Nicky Haslam? To accompany the interviews with Nutcracker designers elsewhere, here are three very different design portfolios tackling the eternal magic of this favourite ballet with unexpected reference points. Sketches by John F Macfarlane for Birmingham Royal Ballet, Antony McDonald for Scottish Ballet and Gerald Scarfe for English National Ballet are seen with production stills alongside.

A delicious new treat is promised at The Royal Opera House for Christmas: a comic opera by Tchaikovsky that brings the wit and fun of a Russian magical folk tale to the stage in a staging of rare opulence. A story of turbulent love, magical rides through the sky with the Devil, and an impossible task - to get a peasant girl a pair of Catherine the Great's slippers - The Tsarina's Slippers has ballets and Cossack dancing as well as a host of singing characters.

A new production by The Royal Opera of Tchaikovsky's The Tsarina's Slippers opens on Friday at Covent Garden, directed by Francesca Zambello, designed by Mikhail Mokrov and Tatiana Noginova, and with an all-Russian cast of principals conducted by Alexandr Polianichko.
