Brad Bird: Rats should crawl or how to deal with creative employees

When Pixar asked me to take over Ratatouille, the project had been in development for five years but was not in any shape to produce as a movie. There was a moment, at the very beginning of my involvement, when I was in a room full of about 30 people. At this stage, the rats in the movie had been articulated. Articulation is where they design how the muscles and controls work on the characters. Because people were worried about the audience’s reaction to rats, all of them were designed to walk on two legs.

I thought that was a mistake. I knew it would be an expensive use of resources, at that point in the process, to rearticulate the rats, but I said, “We have to get them so that they walk on all fours. And Remy, the protagonist rat, has to be able to walk not only on all fours but up on two legs.” Everybody said, “Ugh!” because they had spent a year making the rats look good walking on two legs. If you simply took those models, bent them over, and put them on all fours, their hips didn’t work and things just looked wrong. They were designed to be upright.

One of the guys challenged me. He said, “I want to know why you’re doing this.” Now, I had gone into this film reluctantly. It’s not what I was looking to do after The Incredibles. And there was a part of me that wanted to say, “Because I’m the director, that’s why. Do you want to take this problematic thing over?”

But I stopped and thought for a second. I thought, these guys have been sent down blind alleys for a couple of years. They want to know that I’m not doing anything lightly and that if I’m going to make them do a bunch more work, it’s for a reason. So I said, “This movie is about a rat who wants to enter the human world. We have to make that a visual choice for the character. If you have all of the rats walking on two legs, there’s no separation between him and the other rats. If we have this separation as a visual device, we can see the character make his transformation and choose to be on two legs, and he can become more or less ratty, depending on his emotional state. That brings the audience into the character’s mind.”

I spent six minutes saying all this and the guy was initially scowling. But gradually the scowl went away, and he said, “OK.” Once I gave that answer, everyone felt, “OK, we’re on this ship and we’re going toward a definite destination.”
