If you do too much acting in a lead part in a feature film where you're 40 ft. high, it's rather unattractive. You can see the acting. And it's actually the right thing to do to bring as much of yourself, I believe, to the part as you possibly can - to minimize the amount of theatrical stuff that you need to do.
I used to dream about Gorbachev before he lost power. I'd go into a panic because I was meeting him, and I had nothing to wear. I'd ask my brother what to do, and he'd tell me to wear my dressing gown. I'd tell him I can't - it's too horrible. He'd tell me to wear his as well. So I'd meet Gorbachev wearing two dressing gowns.
