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.

A lot of new dads don't realise that you can't take your 5-year-old along to see something like 'The Avengers.' Modern superhero films are too violent, and the dialogue is far too convoluted for a child.
