Robert Louis Stevenson: People aren’t stupid. This tale is not in my normal style. There are those a few, who might suspect its origins in truth, in a tale of a potion that can transform its hero into a demon.
Jekyll: I am not a hero and it is not a tale.
Hyde: Oh, this feels good. Roomy! Look at all this space! I could put up shelves.
Claire: Where is he? Where's my husband?
Hyde: Search me, love, he was in here a minute ago. Turn my back and whoosh! Not even a tip on the dresser! Men! Oh, this feels so peaceful. Love it. No more boring little doctor yapping away in the corner. Honestly, you have no idea. "Don't do this, don't do that, don't kill her, your turn to shave", and if I'd had one more argument about who was biting the finger nails. Ohhh! Did that bug you, the fingernails? Did he do that when he was with you? We should talk, you and me. We're fellow sufferers. We could have a cup of coffee and a good old chinwag about him. The wife and the ex. Girls together. All friends now; the bastard's dead.
Hyde: The thing about consuming an alter ego, bit like a Chinese. A minute later, you're hungry again. Hello, boys!
Malcolm: The thing is, basically, you may not be stabilized yet. It’s for your own good. Basically
Hyde: Okay, Mr. Basically. Talk to me like you know me again, in public where people can see, and the next sound you hear will be your own neck snapping. Do we now have a basis for communication?
Hyde: I've got rewind. Look at that. (plays Tom's memories back and forth) I've got digital rewind, it's like Sky+ in here.
Alice: What do you hope to achieve, sir?
Jekyll: Your protection.
Alice: With a tale of a magic potion? Do you think anyone will think that’s the truth?
Jekyll: The truth is just a tale told often enough.
Min: Four women locked in a room without a single magazine. It’s like some kind of vile experiment.
Hyde: The next stage of human evolution. How much do you get for that these days?
Min: Do you know what I’m thinking?
Miranda: God forbid you should ever have an unexpressed thought.
Miranda: Ooh! Technology’s running away with me. It’s just no fun being locked up any more.
Min: Like you ever listen when I say that.
Hyde: You’re safe with me.
Claire: You’re a psychopath and I am not safe.
Hyde: I’m a psychopath with superpowers and you’re my girl!
Hyde: I’m so strong, I walk through this funny little world of yours and I don’t notice it. It bores me. But you, you, Mrs. Jackman... you make me weak. I notice you. You’ve never been safer in your life.
Hyde: Ookey dokey, you first.
Claire: Why me?
Hyde: Fantastic arse.
Claire: What are you doing? You're killing him!
Hyde: Trust me, I'm a psychopath.
Claire: Leave him, don't!
Hyde: But I've started.
Claire: You're not going to kill that man. You're not going to kill anyone. From now on, no more killing people, got it?
Hyde: All day, every day without killing someone? What kind of life is that?
Claire: It's called marriage, honey.
Hyde: I’m supposed to be a superman. Why am I not a superman?
