When a place comes across vividly in a novel, it's often compared to a character. I can remember writing teachers who encouraged me to treat setting as if it were a character, to give it three dimensions, to make it come alive, jump off the page.

In putting setting to work, I like to think about long shots and close-ups. The long shot is the overall view of the place in which the characters live - the island, the town, the wide sweep of place. Then we narrow in. The close-up, the tight focus, makes the place different from anywhere else.

One day during filming, George Clooney was wearing his surf shirt and board shorts, and my six-year-old daughter was in the background as an extra, playing in the sand - playing herself. She and Clooney suddenly looked equally Hawaiian, equally related to the place I call home.

I like to add props to render the specificities of place - paintings, food, clothing, signs, infrastructure, music, sayings and slang particular to the region and particular to the character. And props shouldn't just sit there; they should get used.

I come from a family that has always emphasized and enjoyed sports - golf, tennis, football, baseball and the rest.

We started off as Marcus Mumford, which is our singer's name. But then it very quickly became apparent it wasn't really a one-man thing: it was indeed a band. We wanted to give the impression of a family business, and we just liked the ring of Mumford & Sons.

Spanish was my first language. Honestly, I learned to first speak in Spanish, not English, because my poor mother had to go to San Diego every day to work and then come back. And she would come home when I was an infant long after I was asleep.

I met my agent when I was 10 years old on a family skiing vacation. He asked if I was interested in acting, and I had been doing school plays. A couple of years later, I called him up, and I started auditioning.
