AFI's list of the top ten animated films.
1. Snow White and The Seven Dwarves
4. The Lion King
6. Toy Story
7. Beauty and the Beast
10. Finding Nemo
As expected Disney dominates! The only non-Disney film on this list is Shrek at #8 and I don't think it belongs on here anyway. It looks like seniority is king with the first three picks starting with the first feature length animated film Snow White and The Seven Dwarves then the second Pinocchio and the fifth with Bambi. Fantasia, Disney's third feature cartoon gets bumped by Bambi and Simba but that's not unexpected. What I did find unexpected was that Beauty and the Beast didn't rate higher since it is the only animated film ever nominated for Best Picture by the Academy. I would have expected Toy Story to rank higher as well for being the first full-length computer animated film. But Toy Story is not the best Pixar film and I would even say Finding Nemo is better.
The best one of all in my opinion (and once again I am stymied by the voters for completely snubbing it) is The Incredibles which brought computer animation to a whole new level of filmmaking, which I predict we will see even more of in the upcoming Wall-E based on the previews. If you look at the way "shots" are framed in The Incredibles you notice they are made to look as though there is actually a camera and actors performing in front of it, (i.e. Mr. Incredible is partly out of the frame while standing next to his wife, some objects are not in focus as if an actual lense were recording the action.) At times you forget that you are watching a cartoon. Maybe in twenty years the Institute will look back at The Incredibles as the most "incredible" animated film. Ok, that was some cheese, but you get my point.
And what about The Secret of Nimh? C'mon!
