And I like people. I like to know what you're really up to. I'm a bit of a nosey busy body. Why do they do the things they do? Why are they prepared to do the things they do to get what they want? When? Where? Who?

I think I had only been working nine months when I got Star Trek, and it was huge. It was very overwhelming. So that opened my eyes a bit at an early age, kind of how not be frightened when walking into a responsibility of something like villain in Batman, or a Hobbit, or whatever it is.

Every time you need protein, get yourself a boiled egg in. But your main meals would be chicken, or hummus, or white fish. You can lose about a pound a day. But you can do this stuff over a period of time, and you can have your happy days. It's about motivation and it has to be something that's realistic for you to keep up.

There's an abundance of exposure when you start working in American films. Inevitably you become a brand and that has to be controlled.

Then there's your diet. You cut out sugars, fat, soy sauces... anything that's nice. Tea and coffee is replaced by boiling water with lemon. It's amazing how quickly you get into it. There's also herbal tea and a lot of water, obviously... about two litres a day.
