Arson Fahim was five years old when he first saw Roman Polanski's World War Two film The Pianist. Fahim was living at the time in an orphanage for Afghan refugee children in Pakistan. He walked into a room one day where children and staff were watching the film, and on screen a hungry and terrified Polish Jew was playing the piano for a German officer - playing for his life. "What I saw captivated me," Fahim recalled. "I went to bed every night with the image in my head. I remember thinking, 'Wow, how could a piano and the sound of it save someone's life?'"
