Idris Elba

When I look at my body of work, I've played a lot of characters who are morally conflicted - 'I'm right, no I'm wrong, I don't know what to do!' I want to play more characters who don't care as much, and who aren't as measured. They are what they are, no apologies.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
