I loved every second of Catholic church. I loved the sickly sweet rotting-pomegranate smells of the incense. I loved the overwrought altar, the birdbath of holy water, the votive candles; I loved that there was a poor box, the stations of the cross rendered in stained glass on the windows.
I've also worked hard portraying an Ireland which is fast disappearing. Ireland was a very depressed and difficult place in the 1980s, and I've tried to include that in the script. I worked really hard to find the heart of the book.
One of the things I thought a lot about was how can we get the views, for instance, the main plaza, you look up to Telegraph Hill from there and therefore it would be a disaster to close that view off.
