I think it's important that you always transform if you can. That's what I was trained to do. You try and hide yourself as much as you can - that's the key to longevity.

I had a huge imagination. My granddad says I was a bit of a Walter Mitty character.

I have to make my bones with Hollywood to get in. And when I do maybe I'll metamorphose from Mr. Muscles or whatever it is I am now and become an irascible tosser.

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.
