"Pete Docter: Yeah, we - I was just thinking about, like, OK, I've seen a lot of movies about all these different subjects, including - for some reason, I got thinking about the human body and realizing, well, I've seen, like, traveling through the bloodstream and into the, you know, stomach and things. Well, what if we did this in the mind as opposed to the brain? So instead of blood vessels and dendrites, what if it was consciousness and dream production? And that would allow us to have characters that represent emotions. And that felt like, man, that's exactly what animation does best - strong, opinionated, caricatured personalities. And that just got me excited."

"I'm not actually sure if guilt is an emotion. In fact, that was - at the very beginning of this process, we realized, man, we really don't know very much about the subject. So, we better do some research, and we started looking around online. We found some scientists think that there are basically three emotions. Others went up to 27. Others had 16. Some were in the middle. So, we were kind of left with no definitive answer to our basic question - how many are there? Dr. Paul Ekman, who worked in San Francisco - still does - which is where Pixar Animation Studios is - he had, early in his career, identified six. That felt like a nice, manageable number of guys to design and write for. It was anger, fear, sadness, disgust, joy and surprise. And as I was sort of doodling, I was thinking, surprise and fear - probably fairly similar, so let's just lose surprise. And that left us with five."

"The Legend has it, in the mystic land of Prydain, there was once a king so cruel and so evil that even the gods feared him. Since no prison could hold him, he was thrown alive into a crucible of molten iron. There, his demonic spirit was captured in the form of a great Black Cauldron. For uncounted centuries, the large Black Cauldron lay hidden, waiting, while evil men searched for it, knowing whoever possessed it would have the power to resurrect an army of deathless warriors, and with them, rule the world."

"First, I have to say, there is no resemblance between the movie and the book. Having said that, the movie in itself, purely as a movie, I found to be very enjoyable. I had fun watching it. What I would hope is that anyone who sees the movie would certainly enjoy it, but I'd also hope that they'd actually read the book. The book is quite different. It's a very powerful, very moving story, and I think people would find a lot more depth in the book."
