The education is the answer to everything, really, and on so many different levels. The minutiae of life require analytical skills that you learn in being educated, an ability to navigate the very systems that constitute life. They all require some degree of education, and if you don't get it, you're at a real disadvantage.

I would say only be an actress if you genuinely feel the calling, because it's a tough profession.

I never make suggestions. I really don't. I know a lot of actors who get a part and then they dissect it and they want to change it and they want to add stuff. I'm always amazed and so impressed by actors who do that.

Actors need steely determination. It's a tough profession with plenty of knocks along the way. You have to be very determined and never take 'no' for an answer.

I definitely felt frightened [on Skyfall], but never in danger, because they were always so careful about everything. Some of the driving, particularly on that road around the sheer-drop cliff was actually done by stunt driver Ben Collin, who is otherwise known as The Stig from the TV show Pop Gear. He's a brilliant drive, nonetheless, it was terrifying to be careening along when a wrong turn would mean a thousand-foot drop and you're not in control and you want to slow the car down.

I was out on the shooting range twice a week [for Skyfall]. I worked out with a personal trainer for two hours a day, five days a week. So, it was quite demanding!

One of the saddest aspects for me about filming in South Africa was that the real inequalities are still very much in place - and those are economic inequalities.
