I think it was on some sort of island, but it was definitely in a wooded area. A child was in a hollowed out tree or some sort of hole and there were a bunch of fantasy-like creatures with the kid. I think it's an older movie, maybe based on a book? I can't remember crap about it. THIS IS REALLY BOTHERING ME :(
It is not Nim's Island or The Last Mimzy, both of which I think are too childish for what I'm thinking of, but I think they're familiar. It definitely had fairies or sprites or some sort of little mystical creatures, and maybe talking trees? ARG. Do any of you have any clue what I'm talking about?! Maybe start listing fantasy movies that involve kids and cool animatronics/stuff like that. I have to figure this out :(
PAN'S LABYRINTH. GOT IT. YES! MOVIE TIME!
