Like the character I played in Jekyll, we all have different masks we put on for different occasions. As much as we all want to lead decent lives, we're also attracted by the idea that something dark may lurk within us.

I feel old and vulnerable. I now realise that I knew nothing and know nothing, but back when my career was beginning, I thought I was a man when, in fact, I was a dewy-eyed boy who'd not seen an avocado or eaten a tomato.
