"[It] touches on all of the themes that you're talking about in terms of the way we live in our modern life right now. But also it's writing about something that I think has maybe always been here, which is our yearning to connect, our need for intimacy, and the things inside us that prevent us from connecting. And that sort of tension has always been there. So I think, you know, where we're at right now has a particular set of challenges, but what I'm talking about has probably existed as long as we've existed."

"I think the other thing that's been really exciting about it is that as I've talked to people, the variety of reactions for what the movie's about is wide. You know, like some people find it incredibly romantic, some people find it incredibly sad or melancholy, or some people find it creepy, some people find it hopeful."

"I'm gonna fucking kill you. I'm gonna fucking kill you. It's not funny, don't laugh. I'm gonna fucking kill you. I'm gonna fucking kill you. I love you so much I'm gonna fucking kill you."

"Joaquin Phoenix - Theodore Twombly"

"It's how we spend a third of our lives asleep, and maybe that's the time when we feel the most free."

"You know what, I can over-think everything and find a million ways to doubt myself. And since Charles left I've been really thinking about that part of myself and, I've just come to realize that, we're only here briefly. And while I'm here, I wanna allow myself joy. So fuck it."

"The past is just a story we tell ourselves."

"It's like I'm reading a book... and it's a book I deeply love. But I'm reading it slowly now. So the words are really far apart and the spaces between the words are almost infinite. I can still feel you... and the words of our story... but it's in this endless space between the words that I'm finding myself now. It's a place that's not of the physical world. It's where everything else is that I didn't even know existed. I love you so much. But this is where I am now. And this is who I am now. And I need you to let me go. As much as I want to, I can't live in your book any more."

"The heart's not like a box that gets filled up; it expands in size the more you love."

"She's not just a computer."

"Sometimes I think I have felt everything I'm ever gonna feel. And from here on out, I'm not gonna feel anything new. Just lesser versions of what I've already felt."

"You know, I can feel the fear you carry around, and I wish there was something I could do to help you let go of it, because if you could, I don't think you'd feel so alone anymore."

"I feel like I can be anything with you."

"Falling in love is a crazy thing to do. It's like a socially acceptable form of insanity."

"Erica Albright's a bitch. Do you think that's because her family changed their name from Albrecht, or do you think that's because all BU girls are bitches? For the record, she may look like a 34C, but she's getting all kinds of help from our friends at Victoria's Secret. She's a 34B as in barely anything there. False Advertising."

"A Stanford MBA named Roy Raymond wants to buy his wife some lingerie, but he's too embarrassed to shop for it at a department store. He comes up with an idea for a high end place that doesn't make you feel like a pervert. He gets a $40,000 bank loan, borrows another $40,000 from his in-laws, opens a store, and calls it Victoria's Secret. Makes a half million dollars his first year. He starts a catalog, opens three more stores, and after five years, he sells the company to Leslie Wexner and the Limited for four million dollars. Happy ending, right? Except two years later, the company's worth 500 million dollars, and Roy Raymond jumps off the Golden Gate Bridge. Poor guy just wanted to buy his wife a pair of thigh highs."

"[to Mark] You are probably going to be a very successful computer person. But you're going to go through life thinking that girls don't like you because you're a nerd. And I want you to know, from the bottom of my heart, that won't be true. It'll be because you're an asshole."

"You're not an asshole, Mark. You're just trying so hard to be."
