A few years ago, the word was that a new choreographer was showing interesting things. His name was Liam Scarlett, and although he was very young, some work that had been seen in a workshop was looking promising. It was not long before “promising” became actuality, and Scarlett’s first piece, Asphodel Meadows (main picture), was premiered on the Opera House stage.

Here’s a mindboggling statistic. By my calculation, some 330,000 seats are going to be offered for sale in London and Birmingham for just one ballet this Christmas - that’s live seats, not counting the three (yes, three) cinema screenings of foreign Nutcrackers being beamed into the UK on a lot of holiday dates. So the dance industry reckon to sell up to half a million Nutcracker seats mostly in London in a bit over a month?

Ballet has had a difficult relationship with filming for a long time, not only as regards permissions and copyrights from all the people involved, but also in how to frame and light for film a spectacle and action conceived and judged for the stage, live before an audience of a thousand. Perhaps such things held the Royal Ballet back for decades, while the Paris Opera Ballet, the Kirov and the Bolshoi energetically set cameras rolling on their great stars and landmark productions.

Oh, the joys of eccentricity. Welcome to the Vanderhof family of misfits. The head of the household, Grandpa Martin, refuses to pay any taxes, preferring to keep snakes on a hatstand. Good for frightening off the tax inspector, who unexpectedly drops by.

No more is dance the preserve of the few sitting in the theatre - larger companies are leaping hungrily for TV and now cinema screens, having found various ways around the longstanding obstacle of copyright. The BBC is experimenting with live 3D cinema for Saturday's Strictly Come Dancing final, the Royal Ballet is beaming Thursday's performance of The Sleeping Beauty live to the world's cinemas.

In 2006 the thatched house in Lymington on the Hampshire coast which had been the home of Ken Russell (b 1927) for 30 years burned down. All of the director’s original film scripts, including Women in Love, The Devils and Tommy, were destroyed. So was the bulk of the music collection which inspired him to make his groundbreaking films about composers in the 1960s. There is, however, one part of the Russell archive which has survived, for the simple reason that for 50 years it had never once been in his possession.

The star ballerina Sylvie Guillem was rehearsing in London when she heard about the cataclysmic Japanese earthquake last spring, and the devastating tsunami in its aftermath. It was an apocalyptic blow that she felt personally. Since her first visit there as a teenager, the internationally renowned dancer has been drawn back to Japan year after year, winning legions of friends and supporters, the culture’s aesthetic clarity and spareness influencing her taste, and complementing her own evolution from classical ballerina assoluta into contemporary dancer stupenda.

A beguiling shadow play greets and enchants on arrival: the silhouettes of three ballerinas, each performing an arabesque, are cast upon the wall as you enter. The effect, as their softly delineated forms dip and slowly rotate, is mesmerising. It’s also an apt opener to an exhibition devoted to exploring how Degas strove to achieve a sense of fluidity and movement in his paintings of dancers, a subject for which he is chiefly known.

To celebrate theartsdesk's second birthday on Friday, we held a panel discussion on The Art of Performance at Kings Place, London, in the Kings Place Festival.

It may not serve up all that much to get your teeth into, but Bijan Sheibani’s production of this 1959 play by Arnold Wesker looks fantastic on the plate. Giles Cadle’s saucepan-shaped set is framed by a giant chalkboard, scrawled over and over with daily specials in faded lettering; beyond it, the globular lamps and plate-glass window of the Tivoli restaurant can be glimpsed.
