Growing up, I really looked up to the classic Hollywood actors like Spencer Tracy, Robert Mitchum, and Peter Falk. I love character actors - I've never wanted to be the leading guy.

I am the youngest of four children - three boys and one girl. I don't think becoming an actor had anything to do with seeking attention, though. My relationship with my siblings when I was growing up was close and playful.

I was lucky to get into drama school and become a professional actor. No-one ever mentioned the colour of my skin. It's only when I came out of RADA - the Royal Academy of Dramatic Art - that I suddenly realised people started to refer to me as a black actor.

The area where I grew up in Birmingham was very diverse - I was aware of my race but not overly aware of it - and there seemed to be an understanding that we were all very much in the same boat.

We have very strong environmental laws in the United States and elsewhere around the world. The problem is that they're seldom enforced.

The whole climate is changing: the winds, the ocean currents, the storm patterns, snow packs, snowmelt, flooding, droughts. Temperature is just a bit of it.

I have younger friends who are in this pinch where they feel they've been counted out before they've had a chance to prove themselves. They've inherited a lot of debt - not just student debt but environmental debt, political debt. They really feel squeezed.

The continued existence of wildlife and wilderness is important to the quality of life of humans.
