Im mad keen on recycling because Im worried about the next generation and where all this waste were producing is going. It has to stop. I wash out my plastic containers and recycle envelopes, everything I possibly can.

I've always been terrified about not having money. I've been a big saver and a big earner. When I've been out of work, I've always found another job. I never wanted to get into debt, because money was very tight when I was growing up. I never felt deprived, but I couldn't have the things I wanted.

There isn't anything I don't eat, although I'm not too keen on creepy crawly things. Other than that, I'm quite adventurous. I like all types of red meat, and I'm not a fussy eater at all.

Whether it's a good thing or a bad thing, the higher your profile, the more castable you are in TV dramas.
