Although "Dinosaur" intentionally veers from scientific fact in certain aspects of its storytelling, the filmmakers turned to several leading authorities in the world of paleontology and spent considerable time researching their leading dinosaurs to ensure a high degree of accuracy and authenticity in portraying the movement of the characters.
"Dinosaur" was directed by Ralph Zondag and Eric Leighton, produced by Pam Marsden and co-produced by Baker Bloodworth. Zondag is an animation veteran who has served as an animator, storyman, and director on a variety of feature and television projects throughout the industry. Leighton makes his feature directing debut on this project following a distinguished career in stop-motion animation, including an Oscar®-nominated stint as animation supervisor on the acclaimed 1993 Touchstone Pictures release, "Tim Burton's The Nightmare Before Christmas." Marsden, whose background includes a ten-year stint as managing director of the International Theatre Festival in Chicago as well as stage managing assignments for theatrical productions in New York and Los Angeles, makes her Disney debut here as producer. Bloodworth had previously served as associate producer on Disney's "Pocahontas" and has an extensive list of accomplishments in Los Angeles theatre.
Two of the industry's top visual effects experts came on board to help build Disney's digital studio and create a production pipeline capable of handling the demands of this enormously complex motion picture. Neil Krepela (an Oscar® nominee for "2010" and "Cliffhanger" who helped to set up ILM and Boss Films) took on the role of Visual Effects Supervisor. Neil Eskuri, a CG animator and technical director with credits at many of the major effects houses, served as the film's Digital Effects Supervisor.
Production Designer Walter Martishius and Art Director Cristy Maltese were responsible for overseeing the film's overall look.
