The movie was about a princess or well off girl. She has a love of her life but can’t have him because of some curse. She is taken by some sort of gremlins or goblins and taken underground or in caves. She is eventually saved by her version of prince charming.
It was definitely in color, either 80s or 90s kids film that I saw at home back in the 90s. The artwork resembles Troll n Central Park. In English.
