You don't need to follow trends to be stylish.

When I started out in the profession, it was definitely about proving that I was worthy, but after achieving a certain amount of success, I realized I didn't have to prove anything to anybody.

At Cambridge, it was the weirdest culture. Everyone pretended they didn't do any work, yet it was so competitive.

I wanted to play roles which offered new ways of viewing black women and black people in general- and I have done that. And I have always, whether I needed to pay the rent or not, I've always turned down roles which I thought were stereotypical. And so when I look at my body of work in that respect, I am really happy. Because I feel my work does say something positive and that was what I always set out to do.

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.

Getting to travel around the world and go to glamorous locations is certainly not what I had as a kid.

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.
