Three children have become adults since a phone call with Jo Rowling, containing one small clue, persuaded me that there was more to Snape than an unchanging costume, and that even though only three of the books were out at that time, she held the entire massive but delicate narrative in the surest of hands.
Do you know that moment when you paint a landscape as a child and, when you're maybe under seven or something, the sky is just a blue stripe across the top of the paper? And then there's that somewhat disappointing moment when the teacher tells you that the sky actually comes down in amongst all the branches. And it's like life changes at that moment and becomes much more complicated and a little bit more boring, as it's rather tedious to fill in the branches.
I've learned, having been on a lot of sets, the good news is that by definition you are surrounded by experts. They get fired if they're not - unlike in the theatre!
I was coming from a very cerebral, dark, difficult, layered play by Christopher Hampton and doing an action movie in Hollywood (Die Hard) with explosions, and I was holding a gun.
In theater, you've got to be aware of your whole body because it involves stamina. It involves two-and-a-half hours and a sustained release of energy, maybe for six months.
With the best intentions, the job of acting can become a display of accumulated bad habits, trapped instincts and blocked energies. Working with the Alexander Technique has given me sightings of another way... Mind and body, work and life together. Real imaginative freedom.
I never talk about 'Harry Potter' because I think that would rob children of something that's private to them. I think too many things get explained, so I hate talking about it.
And it's a human need to be told stories. The more we're governed by idiots and have no control over our destinies, the more we need to tell stories to each other about who we are, why we are, where we come from, and what might be possible.
I have a photograph at home of Fred Astaire from the knees down with his feet crossed. It's kind of inspiring because it reminds me his feet were bleeding at the end of rehearsals. Yet when you watch him, all you see is freedom. It's a reminder of what the job is about in general, not just being in musicals.
