Iron Man 3

"Ladies, children, sheep... Some people call me a terrorist. I consider myself a teacher. Lesson number one: Heroes, there is no such Thing."

"I have a lot of apologies to make... Nothing's been the same since New York. You experience things, and then they're over. I can't sleep, and when I do I have nightmares. Honestly, there's a hundred people who want to kill me. I hope I can protect the one thing I can't live without..."

"I'm Tony Stark. I build neat stuff, got a great girl, occasionally save the world. So why can't I sleep?"

"Mr Stark, today is the first day of what's left of your life."

"You're not a man. You're nothing more than a maniac. I'm not afraid of you. No politics here: just good old fashioned revenge!"

"You know, it's moments like these when I realize how much of a superhero I am."

"It's Christmas. Take 'em to Church."

"I hope I can protect the one thing I can't live without."
