I've seen Vanessa on stage twice and, of course, in many films, and admired her from afar. Working with her is amazing. A lot of the time I sit in rehearsal thinking, "I wish I could just watch this, because she is amazing" - completely volatile, unpredictable. She'll get up and do a dance, burst into tears. Then you think, "I'm going to have to come on soon. What the hell am I going to do?"
