In rehearsal we did a lot of improvisation, which was very satisfying. It's great to be able to contribute to a play like this. Simon McBurney, the director, has a brilliant vision but he's exacting in what he demands from you. The level of physical training required, for instance, surprised me, with yoga, bench work, stretches and running games. It did motivate me to get fitter, though! The Theatre de Complicite company are a great bunch. You work hard as a team, and you swiftly realise that the end justifies the means.
