"The idea was we would create a whole back-story and a whole back-story for the characters but we would never verbalize it. In the same way, we would move the camera around as if we were in any other location – a shopping mall, a bazaar in the Far East. We would not do what is done so often in this thing where you do a close-up of each monster that you’ve spent money on and you give them each a little vignette. We are going to keep them in the background as if we have wandered into a real place and we are just shooting a real place. So I think that instead of detracting, because we did get some notes and concerns and they were saying, ‘Why don’t we shoot each creature? We spent $100,000 on this creature and it’s just in the background.’ I said, ‘Because that’s where you are flaunting it. When you are flaunting it, you really don’t care. Yes, there is a 20-foot monster lurking in the background but I’m never going to see it again.’ We have some things we designed called the Striders which were creatures that were only seen in the opening shot. They are like headless elephants. I based them on a Dali drawing, the long legged elephant, and we never see them again. Never again and we spent $100,000 or something modeling them. But that’s the whole point. Because we were fighting about the budget and each thing counted and they said, ‘But this is only one shot.’ I said, ‘Yes, but you need it!’ On the first date with a girl you leave a big tip and that’s really impressive. And they go, ‘That’s a 40% tip. What a nice guy.’ It’s the details, you know?"

"Goblin: [Taking the group to the resting place of the Golden Army] Here we are– and there they are. Seventy times seventy soldiers. Sometimes I wish we'd never created them. Bim-bam went the hammers! Whoosh went the furnaces! One of those fires took my legs off. This is as far as I go. I'm not very good with steps. But if you're here to stop him, the Prince, I wish you luck. The Golden Army must not awaken. Undo what we did."

"When Tom Manning gets on the case, things get done. They get done, they get DONE! One hundred percent. I guarantee that."

"[To Hellboy] You've murdered me. You have murdered me. You have ridiculed me, and you– you have brought this unto yourself."

"[About Hellboy's publicity] I suppress each photo, cell phone videos, they cost me a fortune, and then they show up on YouTube. God, I hate YouTube!"

"[Last words] Nuala, my sister..."

"The humans... they will tire of you. They have already turned against you. Leave them. Is it them, or us? Which holocaust should be chosen? We die, and the world will be poorer for it."

"[Defeated, to Hellboy] Kill me. You must. For I will not stop. I cannot. [Hellboy: Sorry, pal. I win. You live.]"

"I am Prince Nuada Silverlance, leader of the Golden Army! Is there anyone here who would dispute my right?"

"[To Hellboy] You may have mused in the past: "Am I mortal?" [Stabs him with a spear] You are now."

"I have returned from exile to wage war and reclaim our land, our birthright! And for that I will call upon the help of all my people and they will answer. The good, the bad– and the worst."

"[To Hellboy about the forest god] Demon! What are you waiting for? This is what you want, isn't it? Look at it. The last of its kind. Like you and I. If you destroy it, the world will never see its kind again– You have more in common with us than with them. You could be a king– If you cannot command, than you must obey."

"[To the forest god's seed] Kill them."

"[After slaying his father; in Gaelic, regretfully] I always loved you, father."

"[After killing an auctioneer] Be quiet. [retrieves the first piece of the Golden Army crown; everyone screams in the background] SIT– DOWN! Proud, empty, hollow things that you are. Let this remind you– why you once feared the dark. [Releases a swarm of flesh-eating faeries unto all the auctioneers]"

"[Liz Sherman: So we have clearance then?] Agent Sherman– Liz– screw ze clearance! We will take zat plane!"

"Zere we are! Your temper – it makes you sloppy! Try to control it, Agent Hellboy, before it controls you. [Walks away, singing cheerfully in German]"

"[To Hellboy] Are you threatening me? Because I zink I can take you."

"You would do the exact same for Liz."

"It's quite obvious it's a breathing apparatus!"

"[To Hellboy] I'll stay with you. You're the best man I know."

"I– I hate it when people stare at me. It makes me feel like a freak. You had no right, Red."
