“You know, Castle's the kind of guy that when he meets somebody, that's a connection for him. He remains connected to the people that he meets. That's the kind of guy he is, be they criminals, gangster rappers, mafia guys, art thieves, whoever it is, he nurtures those relationships.”
“I like to say there's certain things you can't take back: One of them is 'I love you,' and one of them is bullets.”
“Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'”
“Thank God there is a such thing as hiatus. We got the first 'Dr. Horrible' done in six days, we banged it out.”
“I tell you, 'Firefly'? Best job I ever had. Heartbroken when it was canceled, but had it not been canceled, I never would have gotten 'Serenity'. I think 'Serenity' is the most incredible thing I've ever been able to actually get my hands on and do. I can't even tell you how much love I have for that project.”
“I want my job to include a little adventure, a little more of a heightened reality than what I'm actually living. And 'Castle' has that. He gets this opportunity to tail these homicide detectives, and he's driven by that. He's a little immature, but he's obviously loving life.”
“I told myself a while back, 'Love what you do, but don't fall in love with what you do.' That way you won't be brokenhearted if ever it gets canceled five episodes in - which has happened to me.”
“'Castle' is a guy living in a fantasy world. He's in his imagination, writing these stories of murder.”
“I had a Ford F-250. It was a big ol' farm truck, but it wasn't a rig. That's about the biggest I've ever driven. That's what I drove back and forth to high school. I was a poor guy, and it was a truck that my uncle owned and let me drive because I had no money.”
“You know, I endeavor to be more like my older brother. He's very magnetic. He's actually very much like 'Castle' in that people are attracted to him, and just want to be near him. You want to know where my brother is in a crowded room? He's the guy with the crowd around him.”
