We need a number of solutions - we need more efficiency and conservation. Efficiency is a big one. I think car companies need to do a lot better in producing more efficient cars. They have the technology, we just need to demand them as consumers.

Twenty years ago, I was living in a lovely cottage on the edge of Dartmoor but I couldn't afford to run a car.

I don't want to be in my car all day. I love getting up in the morning in Venice and walking my dogs down to the cafe to get my tea, and then perhaps going to a bookstore and sitting and reading, then walking to the beach.

The day I won an Emmy was also the day my father passed away. I received a call from my sister on the way to the ceremony and had to turn my car around and catch the first flight back to Karachi.

Because of that I don't care when I read in the newspaper that I am colourblind. I went through a red light in my car and I stopped when I before a green light. So I must be really colourblind, eh?
