Hmm, it appears some folks are skeptical about the idea of Pixar and Totoro joining together. It's not as far-fetched an idea as it appears. Take a look at these drawings and paintings, created by Pixar artists, that bring their vision of Totoro's world to life. I really enjoy these paintings, and I'm sure you'll like them, too.
The following drawings were created by (in order): Pete Docter (minnesota native and director of Monsters Inc and UP), Peter Sohn (Pixar animator and voice of Emile in Ratatouille), Paul Topolos (concept art for The Incredibles and Ratatouille), and Nate Wragg (end title sequence in Ratatouille). Finally, the CGI Totoro from the previous post was rendered by Richard Vander Wende, who worked on Disney's Aladdin back in 1992.
All of this artwork was created in 2008 for the Totoro Forest Project, a joint venture between the US and Japan to preserve the wilderness of the area outside Tokyo known as "Totoro's Forest." The area has been a personal cause of Hayao Miyazaki for over a decade.
