"Before I read Achebe as a child in Nigeria, I read only foreign children’s books, and so I wrote about the same things I was reading – all my characters were White and the stories were set in England or a generic Westernised country. I had not read books that featured people like me, so I thought that books couldn’t include people like me. Until I discovered Achebe. I didn’t realise it at the time, of course – I was too young to be consciously aware of that sort of thing – but later I would realise that reading Achebe was a turning point. It made me see that it was, in fact, possible for people of colour to exist within literature. Arrow of God has remained one of my favourite novels. Set in 1920s Igboland, it tells the story of a remarkable priest, Ezeulu, and a British administrator, and the ways in which colonialism brought not only political but cultural changes. It is funny and absorbing, moving and beautiful. I love this book."

"From my own personal tastes, my favorite horror film, I think, is a movie called The Innocents, which is based on this Henry James novel Turn of the Screw. The British picture from 1961 with Deborah Kerr as the repressed governess who goes to the faraway estate to take care of these kids who are seemingly possessed by the ghosts of the people who used to haunt the place. It’s a beautifully made movie and it’s not a rock-em’ sock-em’ movie, but its got really great psychological chills in it. And of course, there’s the eternal question as to whether the governess is imagining these things, or are they really happening? And it’s left kind of ambiguous, and it’s a really artful movie. I don’t think it was ever a particularly popular movie. I think a movie like The Haunting, which is somewhat similar, was a little bit more accessible to people than The Innocents, but, for my money, it’s, I think, the best horror film I’ve ever seen."

"Jules Dassin’s gangster film about a robbery and its consequences is a French classic, noir before the word was in use to describe a certain kind of filmmaking. A word is in order here: I was educated in Switzerland, in an era when French-speaking people expected to see French films, so when we were allowed to go to the local cinema at Rolle or Gstaad, we mostly saw French films. British films, except for The Third Man, which is very “European” in tone, seldom played; still less big Hollywood ones. Rififi was a stunner, and an eye-opener, teaching us that French gangsters were a lot more interesting and attractive than our own mobsters, but just as tough, if not tougher. “Julie” Dassin was an American who moved to France, but he captured a whole, pungent slice of French life, and for months everyone at my school (le Rosey) went around trying to sound like Jean Servais, and to talk with a cigarette glued to their lips. Whole scenes from it still play in my fantasies."

"I know it's not cool to go with a soundtrack album but, if I'm honest, this is hugely influential. The film is so wrapped up with my teenage years; when I first saw it I was the same age as the main character and I was somewhat terrified of being somebody like that. To see someone who's so nerdy and yet full of himself is frightening at that age. You wonder, 'Do I do things like this?' You become so self-conscious at high school, you worry about what your peers think, you're terrified of looking weird, or being weird. Somehow the soundtrack represents those feelings. There's lots of British music on there, like the Faces' "Ooh La La" and "Making Time" by the Creation. I grew up in a very small town, so a lot of kids I went to school with mostly listened to rap and rock from the radio. But I did have a group of friends who appreciated films like Rushmore and music like this."
