There's a movie I saw a very long time ago and can't remember what it is. It was made before 2000, I have no idea how long before. It is animated but not exactly a kids movie. There are these very small people who seem to live in a forest hiding from the large, normal-sized people. There is a man and woman (2 of the small people) who get together and the large people are looking for them. They seem to get lost together. In one scene the girl is showing the guy that she can no longer write on her arm with her finger. Than a small person gets captured by a big person and used as a sort of pet. It seemed to be a very artsy and strange movie (even thought it sounds like a weird hallucination). It was so long ago I can't really remember the details clearly. If you have any idea what movie this could have been, any help would be greatly appreciated..
