The Borrower Arrietty
I'm crazy about this movie right now, it's just fantastic and the animation is gorgeous. (I'm sorry this trailer is sort of weird but it's the only one with subtitles). It's loosely based on one of my all time favorite books The Borrowers by Mary Norton, and even though details of the plot are pretty different it's definitely the best film adaptation. On a side note, I'd love to do some illustrations for that book someday...
P.s. you can actually watch the whole movie here.
