"We had a design that was very city-like and very dense, which wasn't quite working. But we went back and looked at a little drawing in the upper corner of the page when the little boy is first coming to look at the Lorax. And we sort of used that as our basis: it's got these big, curvy roads and a couple of building shapes. In some ways, the easier choice would've been to create a Blade Runner-like dystopian future with smog. But of course we wanted to create something that was fun and entertaining, but in some way relates a little more about where we are today, with inflatable bushes and plastic flowers and fake nature that still has a sense of fun, much like Disneyland or Las Vegas or Dubai. So, in the movie that felt like a great way to go but also suggesting that you have to be careful to maintain balance with nature so it can be sustained."
