"I was filming a movie in London, and I drove through Ireland. It was quite beautiful, and the countryside was really remarkable. The contrast between the countryside and Ireland, and the murals there, with Northern Ireland still being a part of the United Kingdom, there's just a stark contrast in those two things. And I found that the art that came out of the conflict was really spectacular because it was about remembering either events or points of view for local neighborhoods, or the rallying cries of one side against the other."
