Nils no Fushigi na Tabi: Movie

Nils Holgersson is a young boy on a farm who is cruel to the animals. But when he catches the farm's little goblin it becomes one prank too many. He is magically shrunk and suddenly the farm animals are out for revenge. He flees on the back of the goose Morten and they join up with a flock of wild geese. Together they travel all over Sweden, with Nils hoping to find a way to become big again.

Note: The film was produced in 1982, but it didn't receive a theatrical release. It became available to the public in 1995 when it got a home release. It wasn't until January 2015 when it would see its first screening in theaters, more than three decades after its production.
