Sub-Saharan Africa is also home to 400 million of the world's poorest people.

I like to stay at home and make cinema in my head.

Working in an office with an array of electronic devices is like trying to get something done at home with half a dozen small children around. The calls for attention are constant.

I maintain the rather old-fashioned view that this is my work and it's in the public arena, but that doesn't entitle everyone to know what happened at home before coming here.

After all my various relationships I find myself now home alone.
