Acting is a sport - especially working with Mark Rylance. There is competition involved. I have to be muscular, challenging, get audiences on side. It's extraordinary how Globe audiences join in - it's like competing at an event - I love it.

Epilepsy is a disease in the shadows. Patients are often reluctant to admit their condition - even to close family, friends or co-workers - because there's still a great deal of stigma and mystery surrounding the disease that plagued such historical figures as Julius Caesar, Edgar Allan Poe and Lewis Carroll.

I'm not likely to be attracted to characters I've already done. I have to be almost frightened by the possibility of taking it on. Over the years, I realise I must enjoy walking that edge; I keep doing it.
