I watched Nimh a lot when I was little, but I barely remember the storyline now. However I really really want to watch it again, because I learned that Derek Jacobi is one of the voices, and he's one of my favorite people ever.
We do own the DVD though, so I should pop that in sometime...
But I wonder how they'll work with the new film. I don't see how it'll work without animation, but I'm always weary about computer animation when it's not done by Pixar, because they seem to be the only ones who know how to consistently have quality animation and a great story line at the same time. And drawn animation is a dead art form now.
