The rules:

1. In the extended entry are quotes from 13 movies. Your job is to identify the movie that each quote came from.
2. Guess as many times as you want, just don't get silly about it.
3. First person to correctly guess each entry gets a point. If there are any left after 24 hours they are worth 2 points.
4. As people guess the films I will strike out those entries and note who got it first.
5. NO cheating!!! That means NO: Google, IMDb, searching my archives etc.!

UPDATE: Holy crap on a stick! I accidentally posted the unedited final version instead of the edited correct version the first time around. If you saw the first version with the answers included please be a sport and sit this one out.

#1 The Truman Show, caught by Dafyd
"If his was more than just a vague ambition, if he was absolutely determined to discover the truth, there's no way we could prevent him."

#2 Batman, caught by Dafyd
"I've been dead once already; it's very liberating. You might think of it as... therapy."

#3 A Beautiful Mind, caught by Tommy
"There has to be a mathematical explanation for how bad that tie is."

#4 The Burbs, caught by Dafyd
"Walter. I know you're in there. That scum-sucking, barking rat of yours has just taken his last dump on my lawn. I find one more- just one- and I'm gonna catch him and staple his ass shut."

#5 The Hulk, caught by Dafyd
"All you've given him is fear. Fear of life."
"Fear. Perhaps. And loneliness, too. Yes. I feel them both. But I have lived completely once. I was so much in love. And she so much wanted a baby. My baby. I could tell from the moment she conceived that it wasn't a son I had given her, but something else. A monster, maybe. I should have put a stop to it right then, but I was curious, and that was my downfall. And as I watched this tiny life unfold, I began to imagine the horror of it, and my curiosity was replaced with compassion. But they took away my chance to cure him. Your father threw me out. I remember that day so well. Every moment. Every sensation. Walking into the house. The feeling of the handle of the knife in my hand. I knew I was doing a father's work, fulfilling a father's mercy... but then she surprised me. It was as if she and the knife merged. You cannot imagine the unbearable finality of it. And in that one moment, I took everything that was dear to me and transformed it into nothing more than a memory."

#6 Young Guns, caught by Kenny
"Damn good riding with you, Chavez."
"Many nights, my friend... Many nights I've put a blade to your throat while you were sleeping. Glad I never killed you, Steve. You're all right..."

"All I was doing was welcoming somebody into the family."
"Larry, we've been welcomed by you, thank you so much, now would you please just drink your fucking milk and shut the fuck up."

#8 The Empire Strikes Back, caught by Tommy
"Oh. I thought they smelled bad on the *outside*."

#9 Superman, caught by Dafyd
"Really, supposing that man had shot you? Is it worth risking your life over ten dollars, two credit cards, a hairbrush, and a lipstick?"
"How did you know that?"
"Know what?"
"You just described the exact contents of my purse."
"Wild guess."

"Right."
"Come on in and experience some of my bullshit."

#12 Mr.Mom, caught by Kenny
"I understand that you little guys start out with your woobies and you think they're great... and they are, they are terrific. But pretty soon, a woobie isn't enough. You're out on the street trying to score an electric blanket, or maybe a quilt. And the next thing you know, you're strung out on bedspreads Ken. That's serious."

#13 Beverly Hills Cop, caught by Kenny
"Coffee grounds..."
"So?"
"You know what this stuff is used for?"
