There's a wild variety of designs made for the movie, from the early heydays to the last moment of tweaks and corrections. Even so, because we had such a small crew, a lot of the sets and characters didn't even get a design sheet or sketch treatment. A vague idea and some back an forth were sometimes enough to arrive at the final elements as they appear in the movie.
Lot of work here, please pick one of the galleries:
