When Cathy Marston was asked to choreograph a new dance adaptation of Jane Eyre for Leeds-based Northern Ballet the cast list was obvious. Aside from Charlotte Brontë's tortured titular heroine, Marston knew that she would need a whole company of female dancers to bring to life the likes of Grace Poole, Bertha Mason, Blanche Ingram and Helen Burns. Add in a couple of male leads to play Rochester and Mr Brocklehurst and it was just about job done.
