Mark Ruffalo

I was an introverted kid; I liked my time alone. And the rest of my family is pretty extroverted, so I felt like a bit of an oddball. They're very gregarious and charming and charismatic people. I always felt like I was struggling as a young person. I think everyone was very surprised to hear that I wanted to be an actor.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

I remember once in junior high school, on a Friday, my mom came home from work and said to my brother and I, 'You know, between us, we have only 27 cents, but we have food in the refrigerator, we have our little garden out back, and we're happy, so we are rich.'
