Production design for The Croods is being handled by French artiste and DreamWorks veteran, Christophe Lautrette. Having served in the animation and art departments on such films as Kung Fu Panda (2008) and A Goofy Movie (1995), Lautrette now occupies one of the most pivotal roles in animated film making. Working closely with directors Chris Sanders and Kirk De Micco, Lautrette has been tasked with creating the overall "look" of the film, establishing a unified aesthetic template for everything from character designs to background color schemes.
In the book, Lilo & Stitch: Collected Stories from the Film's Creators, production designer Paul Felix describes the job as "creating mood" and "establish(ing) a sense of place." He says the job lets you create "a world from the ground up," but that this "great freedom" also comes with the "particular challenge to make it all seem of a piece. [...] As disparate as (the) locations are, our goal (is) to make them feel all a part of the same movie."
While we have to wait until March 22nd 2013 to see the prehistoric world Laurette and co. have conjured up for The Croods, you can get a small taste of the man's immense talent by visiting his blog, Les dessins de Lautrette. While browsing around there, I stumbled across a couple of caveman-themed illustrations that may or may not be related to his work on The Croods. As you've probably guessed, they're posted above.
Last minute addition!
