Then again, if we aren’t always at least a little scared, we’re not doing our job. We’re in a business whose customers want to see something new every time they go to the theater. This means we have to put ourselves at great risk. Our most recent film, WALL·E, is a robot love story set in a post-apocalyptic world full of trash. And our previous movie, Ratatouille, is about a French rat who aspires to be a chef. Talk about unexpected ideas! At the outset of making these movies, we simply didn’t know if they would work. However, since we’re supposed to offer something that isn’t obvious, we bought into somebody’s initial vision and took a chance.
