Now in its third season, the Christmas kiddie-pleaser is the work of young British choreographer Christopher Hampson and acid-penned satirist Gerald Scarfe. It is, as you'd expect from the man who animated Pink Floyd's The Wall, a vivid, exaggerated, Mad Hatter world with wacky costumes and more sauce than a Heinz factory. There are also some fun ideas, such as the snowflakes and icicles leaping from a giant fridge, and brilliant national dances, including Yat-Sen Chang as the Russian bear.
