Mark Ruffalo

"It's a difficult undertaking. I've been married for four years and I see this movie as a cautionary tale about people who've gone deeply out of communication."

"The problem to me is violence. It's not cool to kill somebody or hurt people."

"But in my heart of hearts, this is the kind of thing... this is what everyone is struggling with in their lives - relationships and family. To me, it's always an interesting area to mine. I'm drawn to it."

"People say funny things all the time during really serious moments in life."

"I don't like this idea of Method. I come from that school, but what I was taught was that it's your imagination. You do your homework, and you use your imagination."

"I think of marriage as a garden. You have to tend to it. Respect it, take care of it, feed it. Make sure everyone is getting the right amount of, um, sunlight."
